这些内容相当基础,所以从这里开始。可以使用以下方法生成随机图:
\draw plot[smooth,variable=\t,domain=0:3.5,samples=21] (\t,1.4*rnd-0.7);
下面是一个包含大多数其他元素的 MWE:
\documentclass[tikz,border=3mm]{standalone}
\begin{document}
\begin{tikzpicture}[>=stealth,thick,font=\sffamily\Large\bfseries]
\begin{scope}[local bounding box=L]
\draw[<->] (0,2) |- (3.5,0);
\draw[->] (0,0) -- (3,1.5) coordinate[pos=0.3] (x);
\draw[dashed,red] (x) -| ++ (1,1) node[red,circle,fill,inner sep=3pt]{}
coordinate[pos=0.5] (y);
\path (x) -- (y) coordinate[midway](z);
\draw[red,dashed] (z|-0,0) -- (y);
\end{scope}
%
\begin{scope}[local bounding box=R,xshift=7cm,yshift=0.5cm]
\draw[<-] (0,1.5) -- (0,-1.5);
\draw[->] (-0.5,0) -- (4,0);
\pgfmathsetseed{42}
\draw plot[smooth,variable=\t,domain=0:3.5,samples=21] (\t,1.4*rnd-0.7);
\end{scope}
\path (R.south) node[below]{Sound};
\path (L.south|-R.south) node[below]{Model};
%
\draw[line width=2mm,->,shorten >=2mm,shorten <=2mm]
(L.east) -- node[above]{Synthesis} (L.east-|R.west);
\end{tikzpicture}
\end{document}
