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
