Posted: January 20 Hand In: January 27 IN CLASS Attach This Sheet To Your HW 1. The IPOP relationship of a system S is y ( t ) = Z t -∞ x ( τ ) + Z t e t e ( - τ ) x ( τ ) dτ, -∞ < t < Write down the IRF h(t) and the USR(Unit Step Response) g(t) of the system. 2. The IPOP relation of a SISO system S is: x ( t ) -→ [ S ] -→ y ( t ) y ( t ) = Z t -∞ e - ( t - τ ) x ( τ ) dτ,t ( -∞ , ) . Write down the IRF h ( t,τ ) of S. Then compute its output y(t) given that its input x(t) is x ( t ) = e - ( t - 1) U ( t - 1) + U (2 - t ) ,t ( -∞ , ) . Hints: Decompose x ( t ) into x 1 ( t ) + x 2 ( t ) . 3. Find the Laplace Transform of the following signals: 1
