Electrical Engineering

A continuous signal contains the following two components:
x1(t) = 3 cos 20Ï€t
x2(t) = 3 cos 50Ï€t
(a) Find the minimum required sampling rate to avoidaliasing.
(b) Draw the discrete time signals obtained after sampling, whensampled with Fs = 100 Hz. Explain the disadvantage(s), if any, ofsampling beyond the Nyquist rate.
(c) Assume the sampling rate is Fs= 40 Hz, which components areexposed to aliasing effects? Support your answer by showing“Nyquist intervals” and the aliased frequencies.
