Displaying Records Stored on File > Smoothing the Displayed Records
A digital low-pass filter algorithm can be used to smooth the displayed signal. To enable the low pass filter, tick the filter Active option and enter a cut-off frequency into the Cut-off Frequency box.
The low pass filter set in the display module also acts upon the records in waveform measurement, curve fitting and other modules.
(Note that the digitised record on the data file is preserved, filtering takes place when the record is read from the file.)
