Unformatted text preview: x ( t ) to y 1 ( t ) in the circuit of Figure P1.81 in Lathi. 4. For a certain LTI system, the impulse response h ( t ) = e a ( tt ) u ( tt ). (a) For what values of a and t is the system causal? (b) For what values of a and t is the system BIBO stable? (c) For what values of a and t is the system marginally stable? (d) Compute the output y ( t ) of the system with a =1 and t = 0 in response to the input f ( t ) = e j (2 πt + π/ 4) . How are the input and output related? (e) Compute the output y ( t ) of the system with a =1 and t = 0 in response to the input f ( t ) = cos(2 πt + π/ 4)). How are the input and output related?...
