Chebyshev filters have steeper roll-off and more passband/stopband ripples than Butterworth filters. Chebyshev filters minimize the error between idealized and actual filter characteristic over the range but with ripples in passband. There is a defnite ZERO at -1, number of poles gives the ordef of filter. Magnitude spectrum is equiripple in passband and monotonic in stop band.

Poles are inside the unit circle thus filters are stable(HPF and LPF)
ReplyDeleteThe magnitude response is monotonic in stop band, i.e. flat without ripples, and equiripple in pass band, i.e. ripples have equal magnitude.
