Abstract

A synthesis of digital lattice filters with reduced number of tap multipliers is proposed. The resultant structures have about half as many tap-multipliers as Gray-Markel structures. This reduction is applicable when the numerator of a given transfer function is either a mirror image polynomial or an antimirror image polynomial.
