Beschreibung
Zusammenfassung:	A method and apparatus for the automatic analysis of the electroencephalogram waveform through the evaluation of the waves of the EEG waveform which occur within the frequency range from 3.5 Hz. to 7.0 Hz. within a predetermined time interval, e.g. 10 seconds. A linear ramp signal is generated for the time periods between zero crossovers of the EEG signal which represent a frequency within the 3.5 to 7 Hz. range. The cumulative amplitude that the ramp attains during the predetermined time interval is compared with a predetermined value to indicate a characteristic of the EEG waveform.
