Chebyshev filter - Wikipedia

Chebyshev filters are analog or digital filters that have a steeper roll-off than Butterworth filters, and have either passband ripple (type I) or stopband ripple (type II). Chebyshev filters have the property that they minimize the error between the idealized and the actual filter characteristic over the range of … See more Type I Chebyshev filters are the most common types of Chebyshev filters.
