Discussion
The IIR interpolator subsystem module implements an upsampler followed by an IIR filter. IIR low-pass filter is realized by adding allpass pair subsystem output. Vaiable . The IIR is 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
