Unformatted text preview: jω ) = . 5 1 + jω-. 5 3 + jω , (1) and use p. 290, Example 4.1. Let x ( t ) = e-3 t U ( t ). Find out the response of this LTI system. Question 12: [Basic] p. 346, Problem 4.35(b). No need to do the sketch. Question 13: [Basic] p. 346, Problem 4.36(a). [Optional] If you are interested, ﬁnd the impulse response (b). In reality, people have diﬃculty generating a real “impulse” signal as an input to a LTI system since a real “impulse” requires inﬁnitely large amplitude. As a result, they try to use a diﬀerent input instead. For example, with the input being x ( t ) as described in Problem 4.36, they then record the output y ( t ). This question shows how to derive the impulse response h ( t ) from x ( t ) and y ( t ) when we cannot directly generate an impulse input. Question 14: p. 631, Problem 8.22....
