JOVANOVIC-DOLECEK, G.; M.-ALVAREZ, M. e MARTINEZ, M.. One simple method for the design of multiplierless fir filters. J. appl. res. technol [online]. 2005, vol.3, n.2, pp.125-138. ISSN 2448-6736.
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.
