Rebuild Missing Data

NI System Identification

Rebuild Missing Data

Rebuilds outliers and missing data in the stimulus and response signals of the model.

ParameterDescription
Original SignalDisplays the input Stimulus Signal and Response Signal. You can move the upper and lower limit lines on the graph. The graph automatically scales the x-axis by default.
Processed SignalDisplays the processed Stimulus Signal and Response Signal. You can move the upper and lower limit lines on the graph. The graph automatically scales the x-axis by default.
Input SignalsContains the following options:
  • Stimulus Signal—Specifies the stimulus input to apply to the system. You can select any signal you use before the Rebuild Missing Data step in the project.
  • Response Signal—Specifies the output response from the system. You can select any signal you use before the Rebuild Missing Data step in the project.
ConfigurationContains the following options:
  • Use same limits for both signals—Specifies whether to use the same limits for both the raw stimulus signal and the raw response signal.
  • Specify upper limit—Rebuilds data above the upper limit you specify. Includes the following option:
    • Upper Limit—Specifies the value of the upper limit. The default is infinity.
  • Specify lower limit—Rebuilds data below the lower limit you specify. Includes the following option:
    • Lower Limit—Specifies the value of the lower limit. The default is negative infinity.
  • Results—Returns the number of points this step rebuilds in the stimulus and response signals of the model.
