A parametric family of spline-based finite impulse response filters and a method for finding the optimal parameter
Kristina A. Budunova, Viktor F. Kravchenko · Радиотехника и электроника · 2023
A new parametric family of filters with finite impulse response is proposed based on convolutions of splines with a rectangular impulse. An algorithm for searching for a parameter that optimizes the deviation of the amplitude-frequency characteristic in passbands and suppression bands. A numerical experiment was carried out, which involved comparing research of new filters with window filters and optimal Chebyshev filters.
