Discussion

The IIR interpolator subsystem module implements an upsampler followed by an IIR low-pass filter. The IIR low-pass filter is implemented as an 8th order elliptical filter. The module variable cutoffFreq must be smaller than Fs*0.5/D, where Fs is the sampling rate and D is the interpolation factor.The
