20.9.2.3 Displaying BIS DSA
The Density Spectral Array (DSA) shows changes in the power spectrum distribution over a certain period of
time.
DSA view shows the following information:
■ y-axis: time scale
■ x-axis: signal frequency scale from 0 to 30 Hz
■ Color bar: shows range of power. Red indicates maximum power and blue indicates minimum power.
■ Spectral edge frequency (SEF) trend: It is the white Spectral Edge line superimposed on the graph where
95% of the total power lies on one side of the line (toward the inside of the graph) and 5% lies on the other.
■ The current SEF value: displays above the graph.
