Chebyshev polynomials of the first kind are defined as Tn(x) = cos (n*arccos (x)). These polynomials satisfy the recursion formula. Chebyshev polynomials of the first kind are orthogonal on the interval -1 ≤ x ≤ 1 with respect to the weight function . Chebyshev polynomials of the first kind are special cases of the Jacobi polynomials.

This MATLAB function returns the lowest order n of the Chebyshev Type I filter that loses no more than Rp dB in the passband and has at least Rs dB of attenuation in the stopband.
Sep 05, 2020 · How does Chebyshev Type 2 filter work MATLAB? Chebyshev Type II filters are monotonic in the passband and equiripple in the stopband. Type II filters do not roll off as fast as Type I filters, but are free of passband ripple. cheby2 uses a five-step algorithm: It finds the lowpass analog prototype poles, zeros, and gain using the function cheb2ap.
