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 threshold output before the rate output is calculated.

Suppression Time

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

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).

LPF Cutoff Frequency

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

Interpolation Type

To have the rate data displayed using Piecewise Constant, Piecewise Linear, or Cosine Smoothing interpolation methods.

Data Sampling Frequency

The sampling frequency of the output.
