Low pass all pole monotonic/nonmonotonic filter function synthesis direct by Christoffel-Darboux formula for set of classical orthogonal polynomials
Vlastimir Dragoljub Pavlović, Aleksandar Ilić · 2006
A class of monotonic/nonmonotonic selective low-pass all-polle even and odd order filter functions are derived by Christoffel-Darboux formula for classical orthogonal polynomials. Magnitude characteristics of these filter functions are suitable with respect to selectivity and shape of amplitude characteristics in the pass band. It have great margin of attenuation on the lower part of the pass-band.
