Design criteria for an EEG Alpha Rhythm Monitor

Abstract

<p>Design criteria for construction of a device for monitoring the frequency of the alpha rhythm of the human EEG are presented in this thesis. Power spectral analysis is implemented on a minicomputer system and its limitations are illustrated. The need for a form of pattern recognition of alpha activity is revealed and satisfied subsequently by use of amplitude and duration discrimination. These techniques along with zero-crossing analysis constitute the main ideas which are recommended in the monitor design.</p>
