SI Split Signal VI
Owning Palette: Data Preprocessing VIs
Installed With: System Identification Toolkit
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.
Use the pull-down menu to select an instance of this VI.

SI Split Signal (SISO Waveform)
 | stimulus signal in is the input waveform of the stimulus signal. |
| response signal in is the input waveform of the response signal. |
 | 1st portion (%) specifies the length of the first portion of the stimulus and response signals as a percentage of the length of the original signals. The default is 66. |
 | stimulus signal 1 returns the waveform of the first portion of the stimulus signal. |
| response signal 1 returns the waveform of the first portion of the response signal. |
| stimulus signal 2 returns the waveform of the second portion of the stimulus signal. |
| response signal 2 returns the waveform of the second portion of the response signal. |
SI Split Signal (SISO Array)
 | stimulus signal in is the input array of the stimulus signal. |
| response signal in is the input array of the response signal. |
| 1st portion (%) specifies the length of the first portion of the stimulus and response signals as a percentage of the length of the original signals. The default is 66. |
 | stimulus signal 1 returns the array of the first portion of the stimulus signal. |
