The CIC filter which needs to be designed in digital receiver is discussed.The design procedure of FIR digital filter which is based on Chebyshev approximation theory and used to design compensating filter is analyzed,and the compensating filter designed ac-cording to Remez algorithm is provided.Finally the simulation results verify the validity of the compensating filter to improve the inherent passband attenuation of CIC filter.
