The periodic modulating signal $m(t)$ is shown in the figure. Using Carson's rule. estimate $B_{F M}$ (bandwidth of the FM signal) and $B_{P M}$ (bandwidth of the PM signal) for $k f=\pi \times 10^{4}$ and $k p=\frac{\pi}{4}$. Assume the essential bandwidth of $m(t)$ to consist only up to and including the third harmonic.
