Answer:A
Which of the following operation is done on the sequence in least square design method?
A. Convolution B. DFT C. Circular convolution D. Correlation
Explanation: In a practical design problem, the desired impulse response hd(n) is specified for a finite set of points, say 0 < n > N. In such a case, the correlation sequence can be computed from the finite sequence hd(n).
