Which filter type is described as having ripple in the passband and a sharp cutoff?
- AA Butterworth filter
- BA Chebyshev filter
- CAn active LC filter
- DA passive op-amp filter
Correct answer: B — A Chebyshev filter. From the official ISED question bank, verified word for word.
Why
A Chebyshev filter is the right choice because it is specifically designed to trade a smooth signal for a faster drop-off, creating small ripples (wiggles) in the passband while achieving a very sharp cutoff to block unwanted frequencies.
