A continuous-time system with impulse response h(t) = 5 rect(t) is excited by x(t) = 4 rect(2t) .
(a) Find the response y(t) at time t = 1/2.
(b) Change the excitation from part (a) to xa(t) = x(t ? 1) and keep the same impulse response. What is the new response ya(t) at time t = 1/2?
(c) Change the excitation from part (a) to and keep the same impulse response. What is the new response yb(t) at time t = 1/2?
