Question A-002-012-010

What is the primary advantage of the Chebyshev filter over the Butterworth filter?

Correct Answer

It allows ripple in the passband in return for steeper skirts

Explanation

The Chebyshev filter achieves a sharper transition from passband to stopband (steeper skirts or roll-off) for a given filter order compared to a Butterworth filter, by tolerating amplitude ripples in its passband.
