Suppose that a discrete-time signal x(n) is processed by the system with transfer function H (z)=0.01/(z+0.99) before sent to a ZOH at 100Hz and then a continuous time filter with transfer function H T (s)=1/((s+1)(0.3s+1)) . Determine the DT transfer function of the system when the output is also sampled at 100Hz. Suppose that a continuous time signal x(t) is processed by the following sampled-data system, 0.1 replacing an old analog filter. The discrete-time transfer function is HT(z) = z−0.9
