Question 53
INNAT2 marksNeeds review
The 4-point DFTs of two sequences x[n] and y[n] are X[k] = [1, −j, 1, j] and Y[k] = [1, 3j, 1, −3j], respectively. Assuming z[n] represents the 4-point circular convolution of x[n] and y[n], the value of z[0] is ________ (rounded off to nearest integer).
Note: The DFT of an N-point sequence x[n] is defined as
