B) Chebyshev
C) Bessel
D) elliptic

Question

Quizplus · Accepted Answer

The Bessel filter has the least amount of roll-off compared to the other filter approximations. This means that it has the best phase response and does not introduce significant distortion in the frequency domain. However, it may not have as steep attenuation as the other filters, so the choice also depends on the specific application requirements.
