Subtract Reference

Generate residues by subtracting a reference signal when you want to focus your analysis on signal variation by removing normal ensemble-level behavior such as the ensemble mean.

To compute residues, you must already have a SummaryData dataset with the statistical signals you want to remove. To generate these signals, use Filtering & Averaging > Ensemble Statistics.

  • Signal — Signal to generate residues from. This signal can be the imported data signal, such as a vibration signal, or a derived signal, such as a TSA signal.

  • Signal to subtract — Choose from the list of available statistical signals.

The software stores the results of the computation in a new variable. The new variable name includes the source signal name with the suffix res.
