ABSTRACT:
A band pass filter has a center frequency that may be changed for scanning or sweeping across a frequency range of a desired brain wave to pass selected frequency components of the brain wave. A brain wave amplitude calculator calculates and stores therein the amplitude of the output of the band pass filter for each value of center frequency of the band pass filter. An optimum frequency calculator calculates and outputs a command indicative of an optimum center frequency of the band pass filter on the basis of the respective center frequencies and their amplitudes. A center frequency selector changes the center frequency of the band pass filter in accordance with the command.
