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.
