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 recursive running sum (RRS) filter, known as a cosine filter, and its corresponding expanded versions. As a result, no multipliers are required to implement this filter.
