A multiplierless implementation of cascade integrator comb filter

This paper presents a cascaded integrator comb compensator filter with a multiplierless implementable structure. A second order linear phase filter is realized with minimum error approximation of the coefficients. The compensator filter coefficients are presented in a canonical signed digits form. Presented design can be implemented using low cost hardware units such as add and shift operations. The results show that the compensator filter not only reduces the power consumption but also improves the pass band drop of the CIC filter.
