SI Normalize VI
Owning Palette: Data Preprocessing VIs
Installed With: System Identification Toolkit
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.
If you know the mean and standard deviation of the signals, set mean and std to those values. If you do not provide values for mean and std, this VI estimates the mean and standard deviation of the signals automatically.
Use the pull-down menu to select an instance of this VI.

SI Normalize (SISO Waveform)
 | stimulus signal in is the input waveform of the stimulus signal. | ||||||
| response signal in is the input waveform of the response signal. | ||||||
 | mean contains the mean values you want this VI to use to normalize the stimulus and response signals. If you do not provide a value for mean, this VI uses the actual signal to calculate the mean to use.
| ||||||
 | error in describes error conditions that occur before this VI or function runs.
The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurred before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.
| ||||||
| std contains the standard deviations you want this VI to use to normalize the stimulus and response signals. If you do not provide a value for std, this VI uses the actual signal to calculate the standard deviation to use.
| ||||||
 | stimulus signal out returns the normalized waveform of the stimulus signal. | ||||||
| response signal out returns the normalized waveform of the response signal. | ||||||
 | mean out returns the mean values that this VI uses to normalize the stimulus and response signals.
| ||||||
 | error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces.
Right-click the error out front panel indicator and select Explain Error from the shortcut menu for more information about the error.
