5 - bez- X(z) = 42-4 k=0 5 I=0 where bo = 0.625, b1 = -4, b2 = 7.1875, b3 = -4.765625, bq = -0.28125,65 = 0. 20 = 0.125, Q1 = :-0.84375. 12 = 2.1328125, 03 = -2.546875, 04 1.59375, as = -0.5625. (i) Find the poles and zeros of X(2). Hence, determine and sketch the ROC of X(2). Does it include the unit-circle? (i) Determine the partial fraction expansion of X(z). Hence, identify the terms belonging to the causal and non-causal parts of the signal.
