Q91

A first-order low-pass filter of time constant T is excited with different input signals (with zero initial conditions up to t = 0). Match the excitation signals X, V, Z with the corresponding time responses for t ≥ 0: Match List-I with List-II and select the correct answer: List-I List-II X. Impulse P. 1 - e^ - t T Y. Unit step Q. t - T ( 1 - e^ - t T ) Z. Ramp R. e^ - t T
