Question:

(a) Draw the pole-zero pattern for the signal x1(n) = (rn sin ω0n) u (n) 0 < r < 1
(b) Compute the z-transform X2(z), which corresponds to the pole-zero patterns in part (a).
(c) Compare X1(z) with X2(z). Are they indentical? If not, indicate a method to derive X1(z) from the pole-zero pattern.
