2.1.4. Zero-Input Response (ZIR). 1) Obtain the zero-input response yzir(t). Assume the IC to be y0. Hint: Y (s) = y0 s + 1 + 1 s + 1 U(s) (6) The first term in (6) is the Laplace transform of the ZIR. Take the inverse Laplace transform. 2.1.5. Zero-State Response (ZSR). 1) Obtain the Laplace transform of the zero-state response (yzsr(t)) (i.e., the response of system to input u assuming zero initial conditions). Hint: The second term in (6) is the Laplace transform of the ZSR. Note: We will compute the ZSR for some important inputs u subsequently
