Normalize Data

Normalizes the stimulus and response signals so their mean and standard deviation are 0 and 1, respectively.

ParameterDescription
Stimulus SignalsDisplays the stimulus signal before and after the normalizing process. The graph automatically scales the x-axis by default.
Response SignalsDisplays the response signal before and after the normalizing process. The graph automatically scales the x-axis by default.
Input SignalsContains the following options:
  • Stimulus signal—Specifies the stimulus input to apply to the model.
  • Response signal—Specifies the output response from the model.
Mean Source ConfigurationContains the following options:
  • Stimulus mean source—Specifies the mean value this step uses to normalize the stimulus signal. The default is Auto calculated. Contains the following options:
    • Auto calculated—Specifies that the step automatically calculates the mean to normalize the stimulus signal.
    • User specified—Enables you to specify the mean to normalize the stimulus signal. The default is 0.
    • Value from another block—Specifies a mean from another signal to normalize the stimulus signal.
  • Response mean source—Specifies the mean value this step uses to normalize the response signal. The default is Auto calculated. Contains the following options:
    • Auto calculated—Specifies that the step automatically calculates the mean to normalize the response signal.
    • User specified—Enables you to specify the mean to normalize the response signal. The default is 0.
    • Value from another block—Specifies a mean from another signal to normalize the response signal.
Standard Deviation Source ConfigurationContains the following options:
  • Stimulus standard deviation source—Specifies the standard deviation value this step uses to normalize the stimulus signal. The default is Auto calculated. Contains the following options:
    • Auto calculated—Specifies that the step automatically calculates the standard deviation to normalize the stimulus signal.
    • User specified—Enables you to specify the standard deviation to normalize the stimulus signal. The default is 0.
    • Value from another block—Specifies a standard deviation from another signal to normalize the stimulus signal.
  • Response standard deviation source—Specifies the standard deviation value this step uses to normalize the response signal. The default is Auto calculated. Contains the following options:
    • Auto calculated—Specifies that the step automatically calculates the standard deviation to normalize the response signal.
    • User specified—Enables you to specify the standard deviation to normalize the response signal. The default is 0.
    • Value from another block—Specifies a standard deviation from another signal to normalize the response signal.
