A system is designed for which an input signal emerges delayed by 1.0 seconds, followed by (an echo) another copy of the same signal 1.0 second after that and another copy of the same signal 1.0 second after that. Let the input signal be a(t) = rect(t/4). Let the output signal be b(t). Sketch the output signal and give an expression for b(t) in terms of a(t). View comments (1)
