How does a Chebyshev filter work?
Chebyshev filters are nothing but analog or digital filters. These filters have a steeper roll off & type-1 filter (more pass band ripple) or type-2 filter (stop band ripple) than Butterworth filters. The property of this filter is, it reduces the error between the characteristic of the actual and idealized filter.
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.
Why Chebyshev filter is better than Butterworth 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.
