The low-pass filter is a 4th order Bessel-Thompson filter.
Use the Bandwidth softkey to select the filter's -3 dB cutoff frequency.
The ratio of the input signal's Nyquist frequency and the selected -3 dB cutoff frequency
affects how many points are available in the output, and under some circumstances, there are
no points in the output waveform.
