Transitional multiple-real-pole/multiple-critical-pole transfer functions for lowpass RC-active filter design

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. © 1988, Taylor & Francis Group, LLC.
