Problem
Answer published by the source. Consult the official source to check your work against its answer.
question
(a) Determine the bandwidth occupied by a frequency modulated waveform which results from modulation of a carrier signal by a sinusoidal modulating signal of frequency 3 kHz. The frequency deviation of the modulated signal was found to be equal to 5 kHz. (b) What would be the new bandwidth if the frequency of the modulating signal is increased to 4 kHz and the amplitude is decreased by a factor 2?
