In this paper we propose a new class of selective CIC filters in recursive and nonrecursive form. We illustrate examples of the proposed filter function and calculate integer coefficients of filter impulse response. Detailed comparison between the proposed selective filter class and classical CIC filters is given. The results show that the stopband selectivity can be improved for as much as 40 dB in comparison with classical CIC filtes with the same filter complexity.
