Time Constants

The Time Constants tab allows changing the time constants used for display and averaging.

EEGer has been extensively tested using the default time constants.  Other values may be used but the user must understand the consequences of making radical changes in these values.

• "Average values time constant (seconds)" controls the smoothing time for the average values displayed.
• "Overall percentage time constant(seconds)" controls the smoothing time for the overall percentage value (shown in the upper right corner of the brainwave screen).
• "DC compensation time constant(seconds)" sets the averaging window for determining DC offset corrections.
• "Artifact hold time after end(seconds)" sets how long the artifact state is maintained after the artifact event has ceased (to prepare for more artifacts).
• "Probability time constant(seconds)" controls the smoothing window for maintaining the %over threshold values.
