an angle modulated signal is s(t) = 100 cos(2π fet + 4 sin 2 fmt), where the carrier frequency is fe = 10

MHz and the frequency of the message signal is fm = 1000 Hz.

1. Assume that s(t) is a FM signal. Find its modulation index and effective bandwidth.

2. Assume that s(t) is a PM signal. Find its modulation index and effective bandwidth.
