Name and ID: Name of person to your left: Name of person to your right: 1. The output of a linear, time-invariant system is y ( t ) = e- 2 t sin( t ) U ( t ) when the input is x ( t ) = δ ( t ) + U ( t ). (a) 5 points Find the transfer function H ( s ) of the system. (b) 5 points Find the frequency response H ( iω ) of the system. Is H ( iω ) = H ( s ) | s = iω ? Why? (c) 5 points The input x 1 ( t ) = 5 + cos( t ) + e- t U ( t ) is now applied to the system. Compute the corresponding output, y 1 ( t ). Page 1 of 5 Please go to next page. . . 2. A linear system S 1 is described by the following input-output relation y ( t ) = Z t-∞ 2 e- (...
