A generalized rate change filter architecture
David B. Chester · IEEE International Conference on Acoustics Speech and Signal Processing · 1993
The generalized rate change finite impulse response (FIR) filter architecture described is based on a cascade of single-stage rate-change filter building blocks and allows the decimation and interpolation factors to be prime numbers while preserving the multistage efficiency. The degenerate cases of a generalized decimator and a generalized interpolator are also described.>
