The propagation constant is given by:

2.1 Find the Fourier transform of a rectangular pulse.

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

The sideband frequencies are given by:

Solution:

where k_f is the frequency deviation constant and A_m is the amplitude of the modulating signal.

The power spectral density (PSD) of a random signal is given by:
