Polyphase Resampling Functions

The Intel® IPP functions described in this section build, apply, and free Kaizer-windowed polyphase filters for data resampling. Functions with the Fixed suffix are intended for fixed rational resampling factor and can provide faster speed. Functions without the suffix build universal resampling filter with linear interpolation of filter coefficients and enable a variable factor.

For general description of the polyphase resampling algorithm, see "Multirate Digital Signal Processing" by R. Crochire and L. Rabiner, [Cro83].
