Statement for Linked Answer Questions 80 and 81
Consider the following Amplitude Modulated (AM) signal, where $f_{m}<\mathrm{B}$
\[x_{\mathrm{AM}}(t)=10\left(1+0.5 \sin 2 \pi f_{m} t\right) \cos 2 \pi f_{c} t\]
The average side-band power for the $\text{AM}$ signal given above is
- $25$
- $12.5$
- $6.25$
- $3.125$
