SRC in SDR is also discussed, and two improved structures of CIC filter are presented. The first one is a CIC decimation filter based on polyphase structure and partially sharpening technique, which is suitable for the situation where the requirements in passband attenuation is not very high while the requirements in alias suppression and operating speed are relatively high. The other one is an improved CIC-Rotated Sinc decimator which possesses improved frequency response, low operating rate and low cost in hardware as well.
