Butterworth IIR Filter
The input waveform is filtered with a Butterworth IIR algorithm. The type of the filter is specified by Filter Type as any of the following values:
- lowpass
- highpass
- bandpass
- bandstop
The order of the filter is specified by Filter IIR Order. Also, a number of points equal to Percent Waveform Transient divided by 100 times the input size are eliminated from the beginning of the filtered waveform so the transient response of the filter does not affect further measurements.
