Question

Problem 3A carrier wave of frequency 100 MHz is frequency-modulated by a sinusoidal wave of amplitude20 V and frequency 100 kHz. The frequency sensitivity of the modulator is 25 kHz/V.a. Determine the approximate bandwidth of the FM wave, using Carson's rule. b. Repeat your calculations, assuming that the amplitude of the modulating wave is doubled. Repeat your calculations, assuming that the modulation frequency is doubled.
