END_TYPE

nOrder is the filter order (1-10).
fCutoff is the cut-off frequency in Hz (greater than 0 and less than fSamplingRate /2)
fSamplingRate is the sampling rate f_s in Hz.
nSamplesToFilter is the number of samples (greater than 0) to form the moving average (often referred to as the window size).
fNotchFrequency is the notch frequency in Hz (greater than 0 and less than fSamplingRate /2)
bReset is a Boolean parameter that specifies whether the internal past values should be reset on reconfiguration.
