The impulse response () of a linear invariant continuous time system i – InterviewSolution

InterviewSolution

1.	The impulse response () of a linear invariant continuous time system is given by h() = exp (- 2) (), where () denotes the unit step function. The output of this system to the sinusoidal input () = 2cos(2) for all time , is
Answer» When input is sinusoidal then output is also sinusoidal with same frequency but amplitude and phase changes. Thus amplitude is Phase is tan-1 = 0.25 p Thus y(t) = 2-0.5 cos(2t - 0.25p).
