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. The gain (or amplitude) response, $${\displaystyle G_{n}(\omega )}$$, as a function of angular frequency See more Cauer topology A passive LC Chebyshev low-pass filter may be realized using a Cauer topology. The inductor or capacitor values of a nth-order Chebyshev prototype filter may be calculated from the following equations: See more • Filter design • Bessel filter • Comb filter • Elliptic filter See more Also known as inverse Chebyshev filters, the Type II Chebyshev filter type is less common because it does not roll off as fast as Type I, and … See more The following illustration shows the Chebyshev filters next to other common filter types obtained with the same number of coefficients (fifth order): Chebyshev filters … See more • Media related to Chebyshev filters at Wikimedia Commons See more WebThe Chebyshev Type I and elliptic filters roll off faster but have passband ripple.
