Consider the continuous-time signal x(t) = e-atu(t) where a is a real and positive constant value. Signal x(t) is the input signal of a LTI system, with the following unit impulse response h(t) = te-at u(t). A) Derive an analytical expression for the frequency response of the LTI system, i.e., H(jw), the output signal, i.e., y(t), and its spectrum, i.e., Y (jw) [pt. 15). 2
