Problem 1The sinusoidal modulating wave m(t)=A_{m} \cos \left(2 \pi f_{m} t\right) Is applied to a phase modulator with phase sensitivity kp. The unmodulated carrier wave has frequency fe and amplitude Ac. Determine the spectrum of the resulting phase-modulated wave,assuming that the maximum phase deviation ß = kpAm does not exceed 0.3 radian.
