Abstract :
The modification of the conventional CIC (cascaded-integrator-comb) filter for rational sample rate conversion (SRC) is presented here, where the conversion factor is a ratio of two mutually prime numbers. Specifically, we consider the case where the decimation factor M can be expressed as a product of two integers. The overall filter realization is based on a stepped triangular form of the CIC impulse response and the corresponding expanded cosine filter. This filter performs sampling rate conversion efficiently by using only additions/subtractions making it attractive for software radio (SWR) applications
