+In the default Windowed Sync filter, we have given some reasonable start values there for the filter order: 2 * cutoff freq for highpass and bandpass (for cutoff < 2Hz). 20 to 40% of cutoff freq for lowpass and 1 to 5 Hz for line noise bandstop. The basic rule is to have the transition band as wide (roll-off soft) as possible to avoid artifacts but separated from the signal of interest.

 Filtering the data
 =======
 To remove linear trends, it is often desirable to high-pass filter the
