The z-transform o f the sequence x(n) = u(n) u(n 7) is sampled at five

Question:

The z-transform o f the sequence x(n) = u(n) – u(n – 7) is sampled at five points on the unit circle as follows
x(k) = X(z)|z = ej2πk/5 k = 0, 1, 2, 3, 4
Determine the inverse DFT x’(n) of X(k). Compare it with x(n) and explain the results.
