Graphics, Figures & Tables ⇒ Make a node out of several components

[manuavazquez]

Hi,

is there a way to make a component out of several components so that it can be referenced later?

I'm trying to picture a decisor (in the field of communications),

Code: Select all

\begin{tikzpicture}
	\draw [ultra thick] (10,4.5) -- (10.5,4.5) -- (10.5,5.5) -- (11,5.5);
	\draw (9.8,4.3) rectangle (11.2,5.7);
\end{tikzpicture}

and it would be nice to be able to reference it later as a unit (for drawing arrows and that kind of thing). I guess this is tantamount to build a custom component...isn't it? The thing is I'm starting to learn TikZ and it's a little bit overwhelming

Cheers!!

Perhaps you should take a look at circuitikz.

Thank you very much for your fast reply Thorsten.

I took a look a circuitikz and I can't find such component (I don't think this decisor thing shows up very often in circuits, only in block diagrams for digital communications systems in which there is a modulator, demodulator and stuff like that).

Anyway, I'm wondering...would it possible to include cirkuitikz components in a tikzpicture environment? I take it circuitikz is not a Tikz library but a latex package based on Tikz...am I right?

Greetings.

Then try something like this. The "decisor" (what's the English term?) is drawn as a node with a name you can reference.

Code: Select all

\documentclass[11pt]{article}
\usepackage[T1]{fontenc}
\usepackage{tikz}

\begin{document}
  \begin{tikzpicture}[
    decisor/.style={
      rectangle,
      draw,
      minimum size=1cm,
      inner sep=2pt
    }
  ]
    \node[decisor] (d1) at (1,1) {\tikz\draw[very thick] (0,0) -| +(0.4,0.8) -- (0.8,0.8);};
  \end{tikzpicture}
\end {document}

The node name d1 can be used for other drawing commands.

It works like a charm. Thank you very much.!!

PS: you got me there: "decisor" is a direct translation from Spanish I'm not sure about the appropriate English translation but I think it's "threshold detector"
