Abstract: This paper has addressed the new designs of selective multiplerless Cascaded-Integrator-Comb (CIC) finite impulse response (FIR) filter functions with applications in modern communication systems. The cascading simple filters are used for designs. The resulting filters possess an improved frequency response behaviour. We have studied the influence of cosine prefilter and compensation filter to frequency response characteristics of proposed novel CIC FIR filter functions.
