Design of FIR filters with better performance using Z-window

Abstract

In this paper, a method for designing of FIR filters with very low pass band ripples (PBR) using Z-window has been proposed. The proposed filter design method is the derivative of Kaiser Window (KW). This method produces FIR filters featuring very low PBR and better stop band attenuation (SBA) with exactly marked passband and stopband frequencies with tolerable higher filter order.
