What is the folding frequency for the aliased version of x(n) with sampling rate F?
A. F/D
B. F/4D
C. F/2
D. F/2D
Answer:A
What is the folding frequency for the aliased version of x(n) with sampling rate F?
A. F/D B. F/4D C. F/2 D. F/2D
Explanation: We know that if we reduce the sampling rate simply by selecting every Dth value of x(n), the signal will be an aliased version of x(n), with a folding frequency of F/2D.
