Review Problems
Problem 1: Let the impulse response of an FIR system be given by
h[n] = [n] + a1 [n 1] + a2 [n 2] + a3 [n 3] + a4 [n 4] + a5 [n 5],
where a1 , a2 , ., a5 are all real-valued. The transfer function H (z ) has ve poles at 0, and ve

(i) x1 [n] is a right sided sequence, hence the ROC of its z-transform is |z | > 0.2;
(ii) x2 [n] is a right sided sequence, hence the ROC of its z-transform is |z | > 0.6;
(iii) x3 [n] is a right sided sequence, hence the ROC of its
