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 the filter (See references eg. [Daniels],[Lutovac]), but with ripples in the passband. This type of filter is named after Pafnuty Chebyshev because its mathematical characteristics are deri… WebSep 1, 2013 · The superior performance of the Chebyshev Polynomial Kalman Filter compared to state-of-the-art Gaussian estimators is …
