The Chebyshev IIR filter was designed in scilab, chebyshev filter contains ripples in pass band and stop band in its magnitude spectrum. The order of the chebyshev filter is equal to the number of ripples .LPF and HPF were designed according to the input specifications and then were compared with the values obtained from the graph. We observed that the number of poles in butterworth filter is more than chebyshev filter.
Good
ReplyDeleteChebyshev is a better method to design the fir filters.
ReplyDeleteIn chebyshev filter there are ripples in pass band and monotonic in stop band.
ReplyDeleteRipple are equal to order of filter.
DeleteGood if ripples can be tolerated in the application
ReplyDeleteChebyshev 2 has ripples in stopband
ReplyDeleteChebyshev filter 1 has ripple in passband
