摘要：
Cascaded-integrator-comb (CIC). filters perform sample rate conversion (SRC) efficiently using only additions/subtractions. However, the limited number of tuning parameters may make conventional CIC filters unsuitable for SRC in software radio (SWR) systems. A simple modification to the CIC filter that enhances its SRC performance at the,expense of. requiring a few extra computations per output sample is proposed. Simulation results show that the modified CIC filter outperforms the conventional CIC filter for the purpose of SRC in SWR systems.
