signal. 2. A periodic message signal as shown in Fig.1 is transmitted as an angle modulated signal. The modulation system has carrier frequency fr = 1kHz. Let the signal bandwidth be approximated by its own fifth harmonic frequency. m(1) 0.15 -0.05 d 0.05 0.25 0.1 0.3 0.35 -3 Fig: 1: A periodical signal m(t) a. For the FM, k, = 20, determine the approximate bandwidth of the FM signal. b. For the PM, kp =π/2, determine the approximate bandwidth of the PM signal.
