A periodic message signal m(t) as shown in the figure below is transmitted as an angle-modulated signal. The modulation system has o=27*10 rad/sec. Let the signal bandwidth of m(t) be approximated by its own fifth-harmonic frequency. (a) Find the Bandwidth of the frequency modulation signal assuming k-207. (b) Find the Bandwidth of the phase modulated signal assuming kp-/2. -0.05 a m(t) 3 -3 0.05 + 0.1 0.15 0.2 0.25 0.3 0.35
