4.1 An FM signal has a carrier frequency of 100 MHz and a modulating signal of 10 kHz. Calculate the frequency deviation.

Δf = k_f * A_m

The sideband frequencies are given by:

The frequency deviation is given by:

where X(f,T) is the Fourier transform of the signal over a finite interval T.

Solution:

The propagation constant is given by:
