Digital Chebyshev filter was design using analog filter and given input parameters.In this experiment we given proper comments to codes.We design Chebyshev-1 filter having ripples in passband and no ripple in stopband where ripple indicates the order of filter.The minimum order for Chebyshev filter is 2 because we didn't get the ripple if order is less than two.
Two types of Chebyshev filter were design:
Chebyshev low pass filter
Chebyshev high pass filter
It is easy to find the order just by observing magnitude response
ReplyDeleteChebyshev2 has ripples in stopband
ReplyDeleteRipples were observed in passband
ReplyDeleteChebyshev-II filter has ripples in stopband.
ReplyDeleteChebyshev has ripple in stopbands

ReplyDeleteChebyshev1 has ripples in passband
Preferred over butterworth filter if variation in amplitude are tolerable
ReplyDeleteYes also it gives better frequency response
DeleteIt has less transition band between passband and stopband
