Obtain transfer function H(z) by applying Z-transform to the following difference equation Q3. () (PLO 1, CLO 3, 20) a,y[n + 1] + a,y[n] + a2y[n 1] = box[n + 1] + b,x[n] where a, =; a, = -ao; a2 = 6a;; bo = -az; b, = 7a, . Apply the inverse Z-transform (use method of partial fraction) to the transfer function H(z) and obtain the system response h[n]. (Assume the case of a right sided sequence) (b) (PLO 1, CLO 3, 30)
