(a) What is aliasing, and when does it occur? (b) Can an alias frequency occur in analog signal? Explain your answer. (c) Can aliasing be prevented? If so, give one example of how.

Step 1
This results in the appearance of false frequencies in the sampled signal, which are known as alias frequencies. Aliasing occurs when the sampling rate is less than twice the highest frequency component in the signal, which is known as the Nyquist frequency. Show more…
