A network has a pole at s = –1 and a zero at s = – 2. If this network is excited by sinusoidal input, the output—
-
- leads the input
- lags the input
- is in phase with input
- decays exponentially to zero
- leads the input
Correct Option: B
Since, here pole is nearer to the zero. It means network represents lead network. Hence if network is excited by sinusoidal input the output lags the input. Hence alternative (B) is the correct choice.
