Calculations > Threshold

Parameters

Threshold Type

Specify whether to use a Fixed threshold level or a Percent threshold level. The percentage level will be applied to the entire range of the data.

Threshold Level

Specify a value to use for the threshold level. Will be interpreted as a fixed level or as a percentage based on the Threshold Type parameter.

Suppress Spikes and Gaps

If selected, short on or off periods are removed from the output.

Suppression Time (sec)

The minimum duration of an active or inactive interval when spikes and gaps are suppressed.

Scale Output

If selected, the output is scaled to be equal to the standard deviation where the input signal exceeds the threshold criterion.

Rectify Input

If selected, the input data is rectified.

Low Pass Filter Input

If selected, the input data is low-pass filtered prior to applying the threshold cutoff, but after rectification (if selected).

Low Pass Filter Cutoff Frequency (Hz)

If the low pass option is selected, this is the cutoff frequency used for the low-pass filter.
