Design of CIC Compensator Filter in a Digital IF Receiver

This paper presents a simple multiplier less CIC compensation filter based on the sharpening technique. The proposed filter provides the narrowband compensation, as well as the wideband compensation in the band which is 3/4 of the overall band after decimation. The design parameter is the integer b which depends on the number of the cascaded CIC filters. The values of b are given in the Table obtained using different simulations in MATLAB.
