Chebyshev filters are analog or digital filters having a steeper roll-off than Butterworth filters, and have passband ripple (type I) or stopband ripple (type II). Because cheby2 is generic, it can be extended to accept other inputs, using cheb2ord to generate filter criteria for example.

WebAs rp approaches 0, the elliptical filter becomes a Chebyshev type II filter ( cheby2 ). As rs approaches 0, it becomes a Chebyshev type I filter ( cheby1 ). As both approach 0, it becomes a Butterworth filter ( butter ). The equiripple passband has N maxima or minima (for example, a 5th-order filter has 3 maxima and 2 minima).
