Consider the system represented by the block diagram shown in Fig. 2. The time constant 2 is twice that of the 1. Also, the response of Y lags behind the input by 45. Given X(t)=2sint, and 1=1min, Fig. 2: Block diagram D) Determine the input frequency (). b) Determine the amplitude of the steady-state response Z. c) Determine the overall response of the system (Z(t))
