Data Preprocessing VIs
Owning Palette: System Identification VIs
Installed With: System Identification Toolkit. This topic might not match its corresponding palette in LabVIEW depending on your operating system, licensed product(s), and target.
Use the Data Preprocessing VIs to preprocess the raw data that you acquired from an unknown system.
The VIs on this palette can return general LabVIEW error codes or specific system identification error codes.
| Palette Object | Description |
|---|---|
| SI Bandpass Filter | Applies a bandpass filter to stimulus and response signals. Wire data to the signal in and stimulus signal in inputs to determine the polymorphic instance to use or manually select the instance. |
| SI Detect Feedback | Detects if feedback exists in a system using the impulse response of the system. Wire data to the stimulus signal and response signal inputs to determine the polymorphic instance to use or manually select the instance. |
| SI Down Sampling | Reduces the sampling rate of stimulus and response signals using decimation. Wire data to the stimulus signal in and response signal in inputs to determine the polymorphic instance to use or manually select the instance. |
| SI Lowpass Filter | Applies a lowpass filter to stimulus and response signals. Wire data to the stimulus signal in and response signal in inputs to determine the polymorphic instance to use or manually select the instance. |
| SI Normalize | Normalizes the stimulus and response signals so that their mean and standard deviation are 0 and 1 respectively. Wire data to the stimulus signal in and response signal in inputs to determine the polymorphic instance to use or manually select the instance. |
| SI Rebuild Missing Data | Rebuilds corrupted or missing parts of stimulus and response signals. Wire data to the stimulus signal in and response signal in inputs to determine the polymorphic instance to use or manually select the instance. |
| SI Remove Trend | Removes mean and linear steady-state trends from stimulus and response signals. Wire data to the stimulus signal in and response signal in inputs to determine the polymorphic instance to use or manually select the instance. |
| SI Split Signal | Splits stimulus and response signals into two parts. Use one set of signals for model estimation and one for model validation. Wire data to the stimulus signal in and response signal in inputs to determine the polymorphic instance to use or manually select the instance. |
