The IIR interpolator subsystem implements an upsampler followed by an IIR filter. The IIR low-pass filter is realized by adding allpass pair subsystem output. Vaiable implemented as an 8th order elliptical filter. The module variable cutoffFreq must be smaller than Fs*0.5/D, where Fs is a the sampling rate and D is a the interpolation factor.
The block size of the output pin must be divisible by the interpolation factor D. The input block size equals the output block size divided by D. The input sample rate equals the output sample rate divided by D.
