Find the discrete time unit step response of the system with transfer function G(z) = (z−1)/z(z+1)
Please show the solution to the problem above 15. A discrete-time system has a transfer function (the z transform of its impulse response) H)Ifa unit sequence 24 . If a unit sequence and y[2]? + z + u[n] is applied as an excitation to this system, what are the numerical values of the responses y[O]. y
