Transitional multiple-real-pole/multiple-critical-pole transfer functions for lowpassRC-active filter design
P. Thajchayapong, N. Buabthong · International Journal of Electronics · 1988
A new class of all-pole multiple-real-pole/multiple-critical-pole transfer functions is described. The function characteristics lie between the maximally flat type and the equiripple type. Hence, they provide a lowpass RC-active filter designer with the freedom to trade between the selectivity of the filter response and the filter sensitivity.
