The modulation system has wc = 2π × 103 rad/s. Let the signal bandwidth of m(t) be
approximated by 5 divided by its own period (i.e., its fifth harmonic frequency).
(a) To generate an FM signal with kf = 20л, sketch the frequency-modulated signal SFM(t) in
the time domain.
(b) If a PM signal is generated for m(t) with kp =л/2, sketch the phase-modulated signal
SPM (t) in the time domain.
