Unformatted text preview: n ≤ N1 elsewhere (b) t ( n ) = n ≤ n ≤ N1 2 Nn N ≤ n ≤ 2 N elsewhere Hint: To solve part (b), use the convolution and shifting properties of the ztransform. Problem 5.4 Find the inverse ztransform of each of the following ztransforms: (a) X ( z ) = 1az1 z1a ,  z  >  1 /a  (b) X ( z ) = z 32 z z2 , leftsided sequence Problem 5.5 Evaluate the inverse ztransform of G ( z ) = z 2 ( z +2) 2 ( z 2 +9) for all possible ROCs. 2...
