Answer 1

这是一个简短的建议，因为我现在有空。

\documentclass[tikz]{standalone}
\begin{document}
\begin{tikzpicture}
\begin{scope}[every node/.style={draw,minimum width=1cm}]
    \path (0,0) node[left] (m) {$M$};
    \path (-3,0) node (p) {$P$};
\end{scope}
\draw (m) -- (p) node[midway,fill=white] {$E$} node[midway,below=.5cm] {$t_1$};
\draw plot[smooth,samples=100,domain=0:2.5] (\x,{exp(-2*\x)*(sin(deg(50*\x)))});
\node at (1.5,{-.5cm-.6666em}) {$t_2$};
\node at (1.5,.3) {$D$};
\end{tikzpicture}
\end{document}
