3.Consider an LTI system whose impulse response is G(jω)=1/(a+ jω), a > 0. Suppose that there is an input signal X(jω)=1/(a+ jω). Assume that the output signal is y(t)=
, where u(t) is a unit-step signal. Then which of the following statements is correct?
(A)β+y=-a
(B) βy=-a
(C) β-y=t+a
(D) βy=at
(E) None of the above statements are correct.
