          7.30.  Consider the discrete-time LTI system described by

                                             q[n + 11  = Aq[n] + bx[n]
                                                 Y [n] = cq[n] + h[n]

                (a)  Show that the unit impulse response h[n] of  the system is given by







                (6)  Using  Eq.  (7. ]IT),  find  the  unit  impulse  response  hlnl  of the system  in  Prob.
