Abstract
This paper presents a new optimal recursive digital filter design algorithm to meet simultaneous specifications of magnitude and group delay responses. The technique used is the unconstrained least pth optimization method for a constrained nonlinear programming problem. An illustrative example shows the drastic reduction of group delay ripple in comparison with the all-pass equalizer method.
