In Chebyshev filter response, ripples are seen either in stop band or in pass band. Chebyshev filter has two types:a] Chebyshev 1 which implies ripples in PB and monolithic in SB. b] Chebyshev 2 which implies ripples in SB and monolithic in PB. Order of the Chebyshev filter can be calculated using the number of ripples in its response. The difference in the code of Butterworth filter and Chebyshev filter is the formula used for calculating the parameters of analog filter. Remaining processes of design are identical.
Its hardware implementation is less complicated as compared to that of Butterworth filters.
ReplyDeletethese filters a useful when amplitude is not the main concern
ReplyDeleteChebyshev-III had ripples in passband as well as in stopband.
ReplyDeleteGood explanation
ReplyDeleteChebyshev - II has ripples in stopband and monotonic in passband
ReplyDeleteChebyshev filters display steeper roll offs and hence narrower transition width compared to butterworth filters

ReplyDeletechebyshev 1 was implemented
ReplyDeleteIt has less transition band width
