What does a Chebyshev filter do?

Chebyshev filters are used to separate one band of frequencies from another. Although they cannot match the performance of the windowed-sinc filter, they are more than adequate for many applications.

What is the difference between Butterworth and Chebyshev filter?

As has been emphasized, a Butterworth filter has a maximally-flat pass-band response and the Chebyshev family of filters provides a good attenuation slope. On some occasions the ripples of a Chebyshev filter are not tolerable and the attenuation slope of a Butterworth filter is inadequate.

What are the 2 types of Chebyshev filter *?

the type I Chebyshev filter has ripple in the pass band and a flat stop band, type II is the opposite with a flat pass band and ripple in the stop band.

What is Butterworth and Chebyshev?

A Butterworth filter has a monotonic response without ripple, but a relatively slow transition from the passband to the stopband. A Chebyshev filter has a rapid transition but has ripple in either the stopband or passband.
