Biosignal Average Rectified Value VI

Owning Palette: Biosignal Preprocessing VIs

Requires: Biomedical Toolkit

Calculates the average rectified value (ARV) of a biosignal.

Wire data to the biosignal input to determine the polymorphic instance to use or manually select the instance.

Examples

Biosignal Average Rectified Value (Waveform)

	initialize? specifies whether to initialize the internal state of the VI. This VI performs calculations that are dependent on all previous data since the VI last ran or since you set initialize? to TRUE. When initialize? is TRUE, this VI restarts the calculation dependency. The default is FALSE.
	biosignal specifies the biosignal for which this VI calculates the ARV.
	window info specifies the window information that this VI uses to calculate the ARV. time specifies the time length, in seconds, to average the rectified values. The default value is 0.1.
	error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
	rectification type specifies the type of rectification that this VI uses to calculate the ARV of the biosignal. 0 Absolute (default)—Specifies to use absolute rectification to calculate the ARV. 1 Square—Specifies to use square rectification to calculate the ARV.
	average rectified value returns the ARV of the biosignal.
	error out contains error information. This output provides standard error out functionality.

Biosignal Average Rectified Value (Array)

	initialize? specifies whether to initialize the internal state of the VI. This VI performs calculations that are dependent on all previous data since the VI last ran or since you set initialize? to TRUE. When initialize? is TRUE, this VI restarts the calculation dependency. The default is FALSE.
	biosignal specifies the biosignal for which this VI calculates the ARV.
	window info specifies the window information that this VI uses to calculate the ARV. length specifies the width, in number of samples, to average the rectified values. The default is 100.
	error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
	rectification type specifies the type of rectification that this VI uses to calculate the ARV of the biosignal. 0 Absolute (default)—Specifies to use absolute rectification to calculate the ARV. 1 Square—Specifies to use square rectification to calculate the ARV.
	average rectified value returns the ARV of the biosignal.
	error out contains error information. This output provides standard error out functionality.
