MULTIPLIER-FREE FILTER DESIGN USING LT COMB FILTERS
Gordana Jovanović Doleček, Vlatko Doleček · 2006
This paper present on simple method for multiplier-free finite impulse response (FIR) filter design based on the cascade of comb and linearly tapered comb filters. The stopband frequency determines the length of the comb filter. The method is used for narrowband filters where the passband frequency is not more than 0.1 of the stopband frequency. The sharpening technique is used to satisfy the desired stopband attenuation and the minimum passband ripple.
