Suppose x 1 [n] is an infinite-length, stable (i.e., absolutely summable) sequence with z-transform given by x
Question:
Suppose x1[n] is an infinite-length, stable (i.e., absolutely summable) sequence with z-transform given by
x1(z) = 1/ 1−1/3z−1.
Suppose x2[n] is a finite-length sequence of length N, and the N-point DFT of x2[n] is
X2[k] = X1(z) | z=ej2πk/N’ k = 0, 1…..N – 1,
Determine x2[n].
