(a) Derive and plot the effect of sampling on spectrum of signal band limiled to WHIL
Explanation
The effect of sampling on the spectrum of a band-limited signal is a fundamental concept in signal processing. When a band-limited signal is sampled at a rate lower than the Nyquist rate, the spectrum of the signal is folded back and overlaps with the original spectrum, causing aliasing. The aliasing effect can be reduced by increasing the sampling rate.
