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 pass-band 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.
