A discrete-time system is characterized by the state-space equations with ^-[-]=8-1-4 }] b= d=1 (a) Assuming that y(n7)=0 for n < 0, find y(n7) for the period nT=0 to 5T if x(nT) = 8(T). (b) Repeat part (a) if x(nT) = u(nT) (c) Derive a network for the system. n-1_n-k-l nyo [4 (17)] = [A] [9(0)] + [[A]BX(K) k=0 [y (nt) = c [A][19(0)] + c = [A] BX (K) + DX (nT? n>o k=6 y (0) = cq (0) + DX (0) n-1 {hco= a hent) = CB n>0} unitstipresponse Y (0) = cq (0) + D y(nT) = c [A][{{0}] + C[ AB n>- K=O
