### Solution:

Given, peak voltage of carrier wave ${V}_{0}$  =12 V
Modulation index $\mathrm{\mu }=75\mathrm{%}=\frac{75}{100}$
We know that
Modulation index

So, peak voltage of modulating signal,
$\begin{array}{l}{\mathrm{V}}_{\mathrm{m}}=\mathrm{\mu }×\mathrm{Peak}\text{\hspace{0.17em}}\mathrm{voltage}\\ =\frac{75}{100}×12=9\mathrm{V}\end{array}$
