Generalized equiripple all-pole lowpass filters
ROBERT P. CASTAGNO, Peter B. Aronhime · International Journal of Electronics · 1987
New families of equiripple all-pole lowpass filters are presented which have equiripple passbands and monotonic stopbands. The number of maxima in the pass-band is controlled so that both reduced critical Q and flatter group delay are realized in comparison with Chebyshev filters. Tables of parameters are provided for selected cases of these new filters.
