This question continues my another. My code:
\documentclass{scrartcl}
\usepackage{tikz}
\usetikzlibrary{positioning}
\begin{document}
\begin{tikzpicture}[auto,
signal/.style = coordinate,
block/.style = {draw,
rectangle,
minimum height = 2em,
minimum width = 4em
},
integrator/.style = {block,
(path picture bounding box.south west) -- (path picture bounding box.north east)
}
]
%placing the blocks
\node[signal] (input) {};
\node[block, right = of input] (open-loop controller) {Steuerung};
\node[integrator, right = of open-loop controller] (system) {};
\node[signal, right = of system] (output) {};
%connecting the placed nodes
\draw
[->] (input) -- node {$w(t)$} (open-loop controller);
\draw
[->] (open-loop controller) -- node {$u(t)$} (system);
\draw
[->] (system) -- node {$y(t)$} (output);
\end{tikzpicture}
\end{document}
The system block should have a diagonal line from the left lower corner to the right upper corner:
I tried to solve it with (path picture bounding box.south west) -- (path picture bounding box.north east)
and failed. Is there a way to do it in the ''style section''?
