Abstract

This chapter presents the design of narrowband highpass linear-phase finite impulse response (FIR) filters using the sharpening recursive running sum (RRS) filter and the interpolated finite impulse response (IFIR) structure. The novelty of this technique is based on the use of sharpening RRS filter as an image suppressor in the IFIR structure. In that way, the total number of multiplications per output sample is considerably reduced.
