ONE SIMPLE METHOD FOR THE DESIGN OF MULTIPLIERLESS FIR FILTERS

Abstract

This paper presents one simple method for the design of multiplierless finite Impulse response (FIR) filters by the repeated use of the same filter. The prototype filter Is a cascade of a second order recurslve running sum (RRS) filter, known as a cosine filter, and its corresponding expanded versions. As a result, no multipliers are requlred to implement this filter.
