The amplitude of the side bands of the modulated signal if the carrier signal and message signal amplitudes are $25 \mathrm{~V}$ and $5 \mathrm{~V}$ respectively is
$0.5 \mathrm{~V}$
$2.5 \mathrm{~V}$
$0.2 \mathrm{~V}$
$5 \mathrm{~V}$
Solution
We have
$\mathrm{m}=\frac{\mathrm{A}_{\mathrm{m}}}{\mathrm{A}_{\mathrm{c}}}=\frac{5}{25}=\frac{1}{5}$
So, amplitude of side band $=\frac{\mathrm{mA}_{\mathrm{C}}}{2}=\frac{1}{5} \times \frac{1}{2} \times 25=2.5 \mathrm{~V}$
