In this experiment we used the same technique as we did for butterworth filter. We performed this experiment on SCILAB and same input parameters were given as in butterworth filter for LPF and HPF.
From this experiment we observed that, ripples were present in passband and on the other hand it was monotonic in stopband for LPF and it was vice versa for HPF.For LPF we get exact zero at -1 and for HPF we get exact zero at +1.

Minimum order for a chebyshev filter is 2.
ReplyDeleteThere are two types of Chebyshev Filter as per design and calculations
ReplyDeleteYaa Chebyshev-1 and Chebyshev-2
DeleteChebyshev filter is not monotonic like butterworth if ripples are observed.
ReplyDeleteYes it is not monotonic.
DeleteThe type of Chebyshev will be decided according to ripples in stop band or pass band
ReplyDeleteChebyshev filter has ripples in the frequency response depending on the type
ReplyDeleteChebyshev1 has monotonic stopband
ReplyDeleteChebyshev filters are classified into two types based on the presence of ripples- Chebyshev-I and chebyshev-II
