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