Design of wave digital bandpass filters with simultaneous approximation to the ideal delay and amplitude characteristics

Abstract

A technique for the design of wave digital bandpass filters with amplitude selectivity and phase linearity in a significant portion of the passband is presented. The technique is a nontrivial extension of the lowpass design given by H. Baher et al. (1990). The author considers a design of a sixth-order wave digital bandpass filter as an example. The amplitude and delay responses of the filter are given.<>
