Inputs/Outputs

datatype_icon

signal

The input signal.

This input supports the following data types:

  • Waveform
  • Array of waveforms
  • 1D array of double-precision, floating-point numbers
  • 2D array of double-precision, floating-point numbers
datatype_icon

error in

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Default value: No error

datatype_icon

median

Median value in the input signal.

datatype_icon

mode

Estimated mode of the input signal.

Algorithm for Calculating mode

This node uses a histogram to divide the input signal range into 100 equally-spaced bins, or intervals. mode is the center value of the bin that contains the most values from the input signal.

datatype_icon

mean

Average of the values in the input signal.

datatype_icon

standard deviation

Standard deviation of the values in the input signal.

datatype_icon

variance

Variance of the values in the input signal.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.

Standard Error Behavior

datatype_icon

IQR

Interquartile range in the input signal.

Because the IQR is computed as the difference between the 25th and 75th percentile, this measure of spread is more resistive to outliers than other measures.
datatype_icon

range

Difference in the minimum and maximum values of the input signal.
