Abstract :
In order to solve the problem which the pass band tolerance of the CIC filter is large and the stop band is small in the digital receiver, the paper uses the ISOP filters to compensate it after the analysis about the transfer function of the traditional CIC filter and its spectral characteristics. Finally the simulation result shows that the compensating filter could improve the inherent pass band tolerance of CIC filter effectively.
