Consider an FM modulated signal s (t) = 20 cos[276000f + 0(t)]. The frequency sensitivity %3D = 50 Hz/V and the input message signal m(t) = 3 cos(27250f) a. Determine the bandwidth based on 1% sideband b. Determine the modulated signal SEM (t) c. Determine Szy (f) and sketch the one sided spectrum of the modulated signal d. What is the total average power?
