# Draw a circle node with a cross symbol inside it to resemble a multiplier of a signal modulator

How do I do this in TikZ:

I want to draw a circular node with a cross in it to resemble a multiplier like in the diagram shown in the link below. I can draw a circle but I don't know how to put the cross inside.

-

\documentclass{scrartcl}
\usepackage{tikz}

\begin{document}
\begin{tikzpicture}[cross/.style={path picture={
\draw[black]
(path picture bounding box.south east) -- (path picture bounding box.north west) (path picture bounding box.south west) -- (path picture bounding box.north east);
}}]

\node [draw](A){start};
\node [draw,circle,cross,minimum width=1 cm](B) at (3,0){};
\node [draw](C) at( 5,0){end};
\draw[->] (A) -- (B) -- (C);

\end{tikzpicture}

\end{document}

Awesome! Thanks. –  Mir Apr 6 '11 at 19:24

I full the previous answer with a solution made ​​with the package schemabloc

\documentclass{article}
\usepackage{tikz}
\usepackage{schemabloc}

\begin{document}
{\centering
\begin{tikzpicture}
\sbEntree{dspk}
\sbBloc[5]{band}{Bandpass filter}{dspk}
\sbRelier[\parbox{5em}{DSPK \\ signal}]{dspk}{band}
\sbBlocL{logic}{Logic circuit}{band}
\sbSumb[3]{sum}{logic}
\sbRelier{logic}{sum}
\sbDecaleNoeudy[5]{band}{delay}
\sbBloc[8]{delay}{Delay}{delay}
\sbRelieryx{band-logic}{delay}
\sbRelierxy{delay}{sum}
\sbBlocL{int}{\parbox{5em}{Integrate \& Dump} }{sum}
\sbBlocL{thres}{\parbox{5em}{Treshold \ Device} }{int}
\sbSortie[4]{S}{thres}
\sbRelier[OP]{thres}{S}
\end{tikzpicture}

}

\end{document}



Please note the package requires version 2.1cvs of pgf

Below a solution with four parameters for putting labels in the 4 circle sections. It would be nice to place the args relatively to the shape width/height, but I don't know how it can be done.

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{positioning,calc}

minimum width=6mm,
path picture={
\draw[black]
(path picture bounding box.south east) -- (path picture bounding box.north west)
(path picture bounding box.south west) -- (path picture bounding box.north east);
\node at ($(path picture bounding box.south)+(0,0.13)$)     {\tiny #1};
\node at ($(path picture bounding box.west)+(0.13,0)$)      {\tiny #2};
\node at ($(path picture bounding box.north)+(0,-0.13)$)        {\tiny #3};
\node at ($(path picture bounding box.east)+(-0.13,0)$)     {\tiny #4};
}
}
}

\begin{document}

\begin{tikzpicture}
