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 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.
Keywords: FIR Filters, Multiplierless Filters, Sharpening, Cosine Filters.
Resumen
Este artículo presenta un método simple para el diseño de filtros digitales con respuesta al impulso finita (FIR) sin multiplicadores, usando el mismo filtro varias veces. El filtro prototipo es una cascada de los filtros recursivos corrientes (RRS) de segundo orden conocidos como filtros cosenos. Así mismo se usan versiones expandidas de estos filtros. Como resultado no se necesitan ningunos multiplicadores para implementar este filtro.
