% \section{Introduction}
%
% In several sciences circuit diagrams are necessary in publications.
% Perhaps there are some PostScript tools for typesetting them or
% a drawing program has to be used.
% With \CIRC it is now possible to typeset circuit diagrams using
% \TeX\ commands. The commands
% describe the logical structure of the wiring scheme and \TeX\
% builds the connections according to this structure.
%
% \CIRC defines several electrical symbols such as resistors, capacitors,
% transistors etc. These symbols can be connected with wires in a
% very easy way.
%
% To use \CIRC you only need \MF and \LaTeXe{}. You do not need
% PostScript or any drawing tool. You can expand \CIRC with
% your own symbols, written in \MF.
%
% \CIRC has been implemented as a turtle system. That means, there is
% a current position from where the symbols and wires are drawn.
% It is possible to choose the drawing direction and drawing position.
%
% \CIRC consists of commands in order to
% \begin{Description}{position}
% \item[draw] symbols and wires into the scheme,
% \item[justify] symbols within the scheme,
% \item[link] symbols with wires,
% \item[position] symbols absolutely or relatively.
% \end{Description}
%
% \section{Installation}
%
% Run |circ.ins| through \LaTeX. You will get a couple of
% |*.mf| files. Use \MF to create |*.pk| fonts from all these files.
% These steps depend on your installation.
% For example, type:
% \begin{verbatim}
% mf \mode=localfont; input ciwidko.mf
% gftopk ciwidko.300
% \end{verbatim}
% Do this with all the |*.mf| sources. Copy the resulting |*.tfm|
% and |*.pk| files into appropriate directories.
%
% Copy the |*.sty|, |*.def| files, obtained from |circ.ins| into appropriate
% directories in your |TEXINPUT| path.
%
% Read the documentation carefully.
%
% Enjoy \CIRC.
%
% We added a Makefile which is tested only under |Debian\GNU Linux|
% (running |teTeX|). We would like to get comments whether it works
% under other environments. {\bf Use it at your own risk!}. Type
% \begin{verbatim}
% make
% \end{verbatim}
% to get all files used by \CIRC. Before you type
% \begin{verbatim}
% make install
% \end{verbatim}
% you should check the correct PATH names in the Makefile. (Make sure
% you run |make install| as root.) This will do the the following:
% \begin{enumerate}
% \item Delete old \CIRC files in |TEXINPUT| and |MFINPUT|.
% \item Move the new |TEXINPUT| and |MFINPUT| to the appropriate
% directories
% \item Check the special.map file in the |Fontname| directory
% whether there ary \CIRC related entries and create them
% if failed. (This will ensure that \CIRC fonts will be
% copied into reasonable directories when using |MakeTeXPK|
% or |MakeTeXTFM|.)
% \item Delete old PK and TFM files from \CIRC. (Using old TFM or
% PK files is one of the "Top ten reasons" why failing \CIRC.)
% \end{enumerate}
% To get the documentation type
% \begin{verbatim}
% make doc
% \end{verbatim}
% (generally this is a good idea to create the needed fonts on the
% fly).
%
% Once more: Please report any bug concerning this Makefile, because
% this is the first test and not reliable at all.
%
%
% \section{System requirements}
%
% \CIRC requires \LaTeXe\ and \MF.
%
%\section{Changes}
% Unfortunately a change of the parameters for symbol drawing
% commands had to be made. But now the rules are more consistent and
% easier to remember. Please have a look at section~\ref{pars}.
% Some new symbols were added and the font selection was modified
% to work together with the slides class.
% The appendix has a new design to be clearly arranged.
% Font names have changed too.
%
% The |\<| command is obsolete now and should NOT used anymore.
% A new |\_| command was defined, see section~\ref{position}.
%
% \section{Usage}
%
% \subsection{Preambel}
%
% \CIRC is divided into several parts. To use a part put the suitable
% option in the |\usepackage| command. All parts are included
% in the following example:
%\example{\warp{usepackage[basic,box,gate,oldgate,ic,optics,physics]}\{|circ|\}}
%
% The parts contain:
% \begin{Description}{physics\,:}
% \item[basic\,:] a lot of symbols such as resistors, capacitors, switches,
% diodes, transistors, etc.,
% \item[box\,:] blackbox, oscilloscope, generator and amplifier,
% \item[gate\,:] several logical circuits,
% \item[oldgate\,:] old style logical gates,
% \item[ic\,:] integrated circuits (flip flops, etc.) and
% \item[optics\,:] the optical stuff with lenses, mirrors, etc.
% (see section \ref{optic}),
% \item[physics\,:] some mechanics stuff.
% \end{Description}
% A complete list of available symbols is given in the appendix.
%
% \subsection{Starting a circuit diagram}
%
% It is recommended to draw a sketch with pen and paper before using
% \CIRC.
%
% Every circuit diagram is enclosed in the
% |circuit| environment
% \example{\CB{begin\{circuit\}}{\em size}}
% where {\em size} is an integer
% between 0 and 4 giving the size of symbols and describing text. A size
% of 4 is useful for overhead foils.
%
% All \CIRC macros and the necessary parameters are separated by
% spaces (\Blank). For a clearly arranged \CIRC diagram it is
% advisable to put every command in a separate line (a linebreak
% is interpreted as a blank as it is used in \TeX).
%
% \subsection{Drawing symbols}
% \label{pars}
% The table in the appendix contains a complete list of all
% \CIRC symbols available and corresponding drawing commands.
% The syntax of drawing commands is:
% \example{\warp{}{\sf symbolname}{\em number\Blank
% inscription\Blank{\tt[}specification\_parameter{\tt]}\Blank direction}}
% or for more complex symbols:
% \example{\warp{}{\sf symbolname}{\em number\Blank {\tt[}further\_parameters\tt ]}}
% Note that you can leave out the blank between the symbol-command
% and the following {\em number} parameter. This parameter has to
% be unique in one drawing and is necessary for correct referring
% (see |\atpin| in section \ref{poscmd}).
%
% The symbols can be classified into a lot of different symmetries
% which are summarized in the appendix. There you will find more
% detailed information about the parameters you have to use.
% Generally the drawing direction of the symbol is given with the
% {\em direction} parameter which is |l| (left), |r| (right),
% |u| (up) or |d| (down).
% If there exist 2 different alignments of a symbol for one
% direction (e.g. if the LED-arrows show up or down) the second
% alignment is chosen by capitalization of the {\em direction}
% parameter (|L|, |R|, |U| or |D|).
%
%\iffalse
% Due to the fact, that there are different symbols for different
% drawing directions the right {\em direction} parameter is important.
% The table in the appendix contains valid {\em direction} parameters
% for every drawing command. This may be |h| (horizontal) or |v|
% (vertical) for symbols with the symmetry two; |l| (left), |r| (right),
% |u| (up) and |d| (down) for symbols with the symmetry four or
% for symbols with the symmetry eight |l|, |L|, |r|, |R|, |u|, |U|,
% |d| or |D|. The latter may need further {\em specification} parameter
% in front of the {\em direction} parameter.
% \fi
% Symbols having two dissimilar or more connections may need
% a further {\em specification} parameter in front of the {\em
% direction} parameter.
% This {\em specification} parameter marks the pin
% that should be on the current drawing position (see variable resistor and
% several transistors).
%
% In the appendix {\tt text} was used for the {\em inscription} and the
% necessary {\em number} was set to {\tt n}. Note the position
% at the symbol where the inscription is set.
% The inscription can be suppressed by the \CB{nv} command in front
% of the symbol-command.
%
% By default every \CIRC symbol is marked by a label.
% This label consists of an abbreviation of the symbol indexed by
% the {\em number}. To suppress
% this labeling use \CB{nl} in front of the symbol-command.
%
% Another command affecting the inscription of a symbol is
% \CB{cc}. It is also used in front of a symbol-command and causes the
% change of label-position and inscription-position. By default the
% inscription is typeset left or over the symbol while the labeling
% is done right or under the symbol depending on the vertical or
% horizontal orientation of the symbol.
%
% Some symbols need {\em further\_parameter}s. The usage
% is selfdocumenting in the appendix table.
%
% Junctions can be made by the \CB{.} command
% (\CB{junction})\footnote{Commands within
% parenthesis are synonyms for the last introduced command.}.
% The syntax is:
% \example{\warp{.}{\em number}}
% Every junction needs a {\em number} argument for further referencing.
%
% \subsection{Referencing symbols and pins}
%
% Some commands use reference parameters
% to mark symbols or connections of symbols drawn before.
%
% The {\em symbol\_reference} parameters consist of two parts:
% \example{{\sf symbolname}$\;${\em number}}
%
% The {\em pin\_reference} parameters consist of three parts:
% \example{{\sf symbolname}$\;${\em number}$\;${\sf pinname}}
% These three parts form the {\em reference} parameter.
%
% See the appendix for the pinnames, they are drawn nearby the pins.
% If the symbol has no pregiven ones the standard names |l| for
% the left connection, |r| for the right, |t| for the top and
% |b| for the bottom one will be chosen.
%
% {\em Note that there is no blank between the parts!}
%
% For example, to refer to the \underline{l}eft connection of the
% resistor with the {\em number} 1 the {\em pin\_reference} parameter
% would be
% \example{{\tt R1l}}
% or to refer to the whole symbol the {\em symbol\_reference} is
% \example{{\tt R1}\quad.}
%
%
% At least it is possible to set markers which work like pin references.
% \example{\CB{P}{\em number}}
% sets a marker which can be referred to by |P|{\em number}.
%
% \subsection{Connecting symbols}
%
% Simple connections between the symbols can be made with the
% \CB{-} command, which is an abbreviation of the \CB{wire}
% command (see appendix). The syntax is
% \example{\warp{-}\Blank{\em length}\Blank{\em direction}.}
% The parameter {\em length} is an integer giving the number of
% lengthsteps. In \CIRC wires are build as a queue of characters
% 2.5\,mm each. Thus the length of wire is measured in multiples
% of this length.
%
% The parameter {\em direction} determines the direction. Valid
% values are |l| for left, |r| for right, |u| for up and |d| for
% down. For instance, a wire is drawn to the left with a length of
% 1\,cm (4 units) by typing
% \example{\warp{-\Blank 4\Blank l}}
%
% There are some other line types to connect symbols. The command
% \example{\CB{dashed}\Blank{\em length\Blank direction}}
% draws a dashed line. It is written as the \warp{-} command.
% With
% \example{\CB{bundle}\Blank{\em text\Blank length\Blank direction} \\
% \einruck\CB{wwire}\Blank{\em text\Blank length\Blank direction}}
% a bundle of wire could be drawn or a pair of wire, respectively.
% You can use \CB{=} as an abbreviation of |\wwire|.
% The {\em text} may contain any comments.
%
% To connect the drawing position horizontally or vertically with
% a certain pin of a symbol by using a reference, the useful
% commands \CB{htopin} and \CB{vtopin} exist.
% The syntax is:
% \example{\warp{htopin}\Blank{\em pin\_reference} \\
% \einruck\warp{vtopin}\Blank{\em pin\_reference}}
% Provided that the resistor |R1| defined before by a |\R| command,
% the command
% \example{\warp{vtopin\Blank R1l}}
% draws a vertical wire up to this height, where the resistor numbered
% with |1| (|R1|) is situated. |\htopin| does the same but horizontally.
%
% The connection will be done by default with the \CB{wire} command.
% To change the type of the connection use the \CB{by} command.
% The syntax is:
% \example{\warp{by\{}{\em command\/}|\}|}
% where {\em command} can be one of the following: \CB{wire} (\CB{-}), \CB{dashed},
% \mbox{\CB{bundle}\Blank{\em text}}, \mbox{\CB{wwire}\Blank{\em text}}
% or \CB{oa} (which is declared in the optics part, see section \ref{optic}).
%
% For example, the command
% \example{\warp{by\{}\warp{dashed\}}}
% changes the drawing style from \warp{[hv]topin} to a dashed lines.
% Do not forget to switch back to wires using
% \example{\warp{by\{}\warp{wire\}}}
% to end the dashed lines.
%
% Note that it is usually necessary to combine the |htopin|- and
% |vtopin| commands, because these commands draw {\em only} horizontally
% or vertically to the x- or the y-coordinates
% of the given pin.
%
% \subsection{\label{poscmd}Positioning commands}
% \label{position}
% Positioning commands are used to change the current
% drawing position.
%
% The direct positioning command \CB{at} (\CB{from}) sets the drawing position
% to an absolute coordinate.
% \example{\warp{at\{{\em x}\}\Blank\{{\em y}\}\Blank}}
% sets the drawing position to the point ({\em x},{\em y}) in the coordinate
% system, where {\em x} and {\em y} are integers counting the number of
% arbitrary units (2.5\,mm). \CIRC starts drawing at $(0,0)$.
%
% It is recommended to avoid the absolute positioning of symbols, because
% it tends to destroy the logical structure of the circuit diagram.
%
% The drawing position can be changed in relation to the current position
% with the indirect positioning command \CB{moverel} (\CB{shift}).
% \example{\warp{moverel\{{\em x}\}\Blank\{{\em y}\}\Blank}}
% moves the drawing position {\em x} units to the right
% and {\em y} units upwards.
%
% The command \CB{atpin} (\CB{frompin}) sets the drawing
% position to a reference pin.
% \example{\warp{atpin}\Blank{\em pin\_reference}}
% allows further drawing starting from the reference pin. For example,
% \example{\warp{atpin C2r}}
% sets the drawing position to the right pin of the capacitor numbered 2.
%
% In a lot of cases a command like |\-| is useful, but it should
% not draw the line. |\_| satisfy this need. As you know from
% |\-| a {\em length} and a {\em direction} must be specified.
%
% \subsection{Justify commands}
%
% The command \CB{hcenterto} forces horizontal centering
% according to a symbol referred to. The command \CB{vcenterto} does the
% same but vertically.
% The command \CB{centerto} centers the following symbol according to the
% reference symbol
% horizontally or vertically depending on the drawing direction of
% the symbol beeing drawn.
%
% The syntax is:
% \example{\warp{hcenterto}\Blank{\em symbol\_reference} \\
% \einruck\warp{vcenterto}\Blank{\em symbol\_reference} \\
% \einruck\warp{centerto}\Blank{\em symbol\_reference}}
% For example,
% \example{\warp{hcenterto L4}}
% would force horizontal centering according to the coil numbered 4.
%
% \subsection{Text commands}
%
% The command
% \example{\CB{put}|\{|{\em text}|\}|}
% puts {\em text} at the current drawing position.
% It can be used in the same way as the \warp{put} command of the
% \LaTeX |picture| environment, but the coordinates have to be omitted
% (because they are given by the current drawing position).
%
% To comment something the commands
% \example{\CB{Utext}\Blank{\em text\Blank{\tt from}\Blank pin\_reference1\Blank{\tt to}\Blank pin\_reference2} \\
% \einruck\CB{centertext}\Blank{\em text\Blank{\tt from}\Blank pin\_reference1\Blank{\tt to}\Blank pin\_reference2}}
% can be used. \warp{centertext} prints {\em text} centered between
% {\em pin\_reference1} and {\em pin\_reference2}.
% \warp{Utext} additionally draws an arrow from
% {\em pin\_reference1} to {\em pin\_reference2}.
% Note that the reference pins must have the same x- or y-coordinate.
%
% To write overlapping information like the \TeX\ commands
% \warp{rlap} and \warp{llap} the following commands are used:
% \example{\CB{blap}|\{|{\em text}|\}| \\
% \einruck\CB{tlap}|\{|{\em text}|\}|}
% They put {\em text} which overlap to the bottom or the top, respectively.

% \subsection{Example}
%
%A simple example is the diagram showing a circuit which is used for measuring
%the amplification of current by a transistor.

%\end{circuit}
%\vskip 4mm
%
%How to cope with such sketches?
%
%First of all, it is necessary to decide, which symbol should be the
%first one.
%The transistor seems to be a good choice to begin with in this
%special case. The command \CB{npn} produces a npn-transistor
%(see appendix); so the first line is
%\example{\warp{npn1 {?} B l}}
%which names the transistor |npn1| for further reference.
%Instead of |{?}| any text describing the specific transistor
%may be written. (Unfortunately this doesn't work today. See
%future plans.) The third parameter |B| means, that the
%\underline{b}ase of the transistor should be on the current
%drawing position. Further more |C| for \underline{c}ollector
%or |E| for the \underline{e}mitter contact would be possible.
%The last parameter gives the direction, in this case the
%base contact points to the \underline{l}eft (|l|).
%
%Use
%\example{\warp{frompin npn1C}}
%to continue drawing from the collector, and type
%\example{\warp{- 1 u}}
%to draw the needed wire \underline{u}pwards
%to connect the amperemeter to measure $I_C$ which is created by the command
%\example{\warp{nl}\warp{A1 \{\$I\_C\$\} u}}\qquad .
%
%The command \CB{nl} in front of the amperemeter avoids the default
%inscription of "$I_1$" because this would not make any sense in this
%case. Instead, the labeling is $I_C$. The last parameter {\tt u}
%marks the direction (\underline{u}p).
%
%To draw the resistor connected with the base of the transistor
%the proceeding is the same: use
%
%|\atpin npn1B |
%to set drawing position (different from the current position),
%
%|\- 1 l |
%to draw a piece of wire to the left and
%
%|\R1 {510\kohm} l |
%for the resistor itself.
%
%A further horizontal piece of wire connects the resistor with the
%second amperemeter: |\- 1 l |.
%
%The second amperemeter, measuring the current of the base ($I_B$),
%would look nice at if drawn the same height as the first one,
%measuring ($I_C$).
%Measuring the length of wire needed to match the same height would be
%difficult and a change of the diagram would cause further changes in
%order to maintain the desired position.
%Therefore it is advisable to use
%\example{\CB{centerto} {\tt A1}\quad \warp{nl}\warp{A2 \{\$I\_B\$\} u}}
%which leeds to the intended centering automatically. Because of the
%\underline{u}p orientation of {\tt A2}, the centering is the same as
%in the vertical direction.
%
%A vertical connection is needed to connect the amperemeter
%with {$R_1$}. This may be done by
%\example{\warp{frompin A2b} \\
% \einruck\warp{vtopin R1l}}
%which draw a wire down to the horizontal wire, starting at
%|A2b|. Instead of the second line |\vtopin npn1B| would do the same job
%because the horizontal position is irrelevant for \CB{vtopin}.
%
%To connect the two amperemeters the drawing position is set to |A1t|,
%from where a wire is drawn upwards and a junction point is marked
%at that point by using
%\example{\warp{frompin A1t} \\
% \einruck\warp{- 1 u} \\
% \einruck\warp{.1}}
%The commands for connecting the second amperemeter are:
%\example{\warp{frompin A2t} \\
% \einruck\warp{vtopin .1} \\
% \einruck\warp{htopin .1}}
%The combination of \CB{htopin} and \CB{vtopin} is very useful
%to connect two points with an edge of wire.
%The driving voltage is typeset by
%\example{\warp{- 1 u} \\
% \einruck\warp{cc}\warp{connection1 \{\$U\_b\$\} c u}}
%because it looks better to put the inscription of the voltage on the
%right. That is why the prefix \CB{cc} is used in front of
%the \warp{connection} command.
%
%Finally the emitter contact leads to the ground:
%\example{\warp{frompin npn1E} \\
% \einruck\warp{- 1 d} \\
% \einruck\warp{GND1}}
%
%The whole example once more in an overview:
%\begin{verbatim}
%\begin{circuit}0
%\npn1 {?} B l % transistor
%\frompin npn1C % draw from collector
%\- 1 u % some wire
%\nl\A1 {$I_C$} u % amperemeter for current of collector

%\- 1 l % some wire

% \section{\label{optic}Optics}
%
% If the |optics| option is given in the |\usepackage| command, the
% creation of simple optical diagrams is possible.
%
% The optical axis can be drawn with the \CB{oa} command, which
% creates a dashed line.
% The optical symbols
% which are available are listed at the end of the appendix.
%
% Here is an example for using |optics|. With the knowledge
% of drawing circuits the following code will speak for itself.

% \section{Some hints for \CIRC programmers}
%
% Here are some hints to add further symbols to \CIRC.
%
% Before creating any new symbol consult very carefully the file |csym.mf|.
% It contains a lot of very useful definitions to simplify writing new symbols.
% Examples for the use of these definitions are given in the files
% |ciwidko.mf| and |optic.mf|.
% When possible it is strongly recommended to use the \MF commands
% \begin{Description}{|fourfourchars|}
% \item[|twochars|] for symbols with the symmetry two,
% \item[|fourchars|] for symmetry four and
% \item[|fourfourchars|] for symmetry eight,
% \end{Description}
% because the definition of the corresponding \TeX\ command
% will need only one line! If there are any problems with \MF{}
% do not hesitate to contact the authors.
%
% A new option file with the extension |def|,
% for instance |newcirc.def|, has to be created to include
% the written symbols. To include the new definitions add
% |newcirc| to the options in the \warp{usepackage} command:
% \example{\warp{usepackage[basic,newcirc]\{circ\}}\qquad .}
%
% The \CIRC-command \CB{freecirc} has to be used to start the
% definitions of new commands in the file |newcirc.def|.
% This ensures, that the asterix (`*') becomes active, because
% all internal \CIRC commands contain the asterix. It is comparable to
% \LaTeX 's \warp{makeatletter}. The \CIRC-command \CB{protectcirc}
% has to be used at the end of the file |newcirc.def|
% in order to restore the former
% behaviour (comparable to \warp{makeatother}).
%
% The \CB{cdef*} commands are strongly recommended to declare commands
% with the new symbols, because only one line is needed for the definition.
% The files |basic.def| or |optics.def| contain examples for \warp{cdef} and
% related commands, which are defined in |circ.sty|.
%
% To ensure that the new symbols are inserted in the right
% magnification the command \CB{extracircinit} may be used.
% It can be used in the same way as \warp{opticfontinit} is used
% in |optics.def|. Both are defined in |circ.sty| as \warp{relax}
% and are called when a new diagram is initialized. If it is necessary
% to do any operations before starting a circuit diagram, then
% it is possible to redefine \warp{extracircinit} to do the job.
%
% \section{Future plans}
% \CIRC is still under development. A lot of users need
% additional symbols or have other wishes. In most of the cases there is
% a quick solution, but to give \CIRC the ability to be an easy
% extendable tool (and to add more potentiality) it has to be rewritten.
% Until this is done there could happen the following steps:
%\begin{itemize}
%\item solve the problem of inscriptions for transistors
%\item redesign some symbols and reimplement the \MF sources
%\item rewrite the font selection to fix some ugly effects
%\item add color support and build a \MP port
%\item use the NFSS2 to make different linethicknesses available
%\item describe the link between \TeX\ and \META
%\item update the documentation every time
%\end{itemize}
%
%
% \section{Contacting the authors}
% Any bug reports, remarks, proposals for new options and symbols,
% any improvements to both the code or the documentation
% as well as some nice postcards are welcome.

If you want to generate an index for the circ-package please
run "makeindex" with the style-file "circ.ist" on "circ.idx".
Using EM-TeX the command line is: makeindx -s circ.ist circ.idx
To get the right pagenumbers in the index and the table of
contents, run LaTeX on "circ.drv" and makeindex in the following
way:
latex circ.drv
makeindx -s circ.ist circ.idx
latex circ.drv
makeindx -s circ.ist circ.idx
latex circ.drv
