COHERENCE

Coherence measures the phase relationship between two raw brainwave signals. When the

peaks and valleys of two brainwaves coincide they are in phase. Coherence measures this

relationship by subtracting each raw data point from the corresponding data point of the

second channel. The difference is then compared over a user selectable number of data

points. If the difference is uniform the signals are more in phase than if the difference varies

greatly.
