An Alternative Design for a Multiple-Real-Pole/Multiple-Critical-Pole All-Pole Equiripple RC Active Low-Pass Filter

A design technique for a class of all-pole transfer functions with multiple real poles and multiple critical poles and equiripple passband magnitude response is described. It is seen as an alternative design which is mathematically simpler than the generalized method previously proposed [8]. it is useful for the designer who is more familiar with the simultaneous linear equations than the optimization using linear programming. © 1986 IEEE.
