Absolute Band Power 1

Absolute Band Power 1

The analysis of Absolute Band Power shows the Y-axis power value of the power spectrum of the specific frequency data for each channel. Before performing this analysis, in order to obtain the absolute power band spectrum it is necessary to use a moving window together. The moving window analysis is explained in the Method of Analysis of this chapter in detail. Please refer to it. The user should select Moving Window in the analysis tool bar at first, configure the window size and the overlap ratio, and then click this analysis method. And the frequency setting dialog box will pop up. When the specific bandwidth for analysis is configured into this frequency setting dialog box, it is possible to analyze the absolute power value of that bandwidth. The result is shown on the display window for each channel as below. The resulting graph that appears on this single screen is an absolute power value. If you wish to check out the result of another graph, it is necessary to use the dynamic function on the bottom of the display window. Besides, if you would like to check out all the absolute power values of the windows on a single screen, select History Mode from the pop-up menu that appears by clicking the right button of the mouse.
