Envelope (Pro Only)
Envelope is a curve “enveloping” the source data. It is tangent to every peak in the source dataset. Origin obtains the upper, lower, or both envelopes of the source data by applying a local maximum method combined with a cubic spline interpolation.
To use Decimation:
- Make a workbook or a graph active.
- Select Analysis: Signal Processing: Envelope from the Origin menu.
