Smoothing

To access data smoothing options:

1. Click the Smoothing icon on the NDE ribbon.

   

   The Smoothing window appears.

   

2. The Smoothing Parameters area allows you to choose the Expansion Order. This can be any discrete value between 1 and 150.
3. If appropriate, check the Enforce Causality check box.
4. If appropriate, check the Create a new data set containing the smoothed data check box. If selected, the smoothed data appears alongside the original data.
5. Click OK.

The Data View Pane updates. The following image shows a plotted result with Create a new data set containing the smoothed data unchecked and checked.

A least-squares polynomial fit of the specified order is used to interpolate new data points for the magnitude and phase components of the S-parameters.
