PURPOSE: To provide various kinds of physiological data by determining the type of sleep of a testee and whether it is an awakening or not based on electroencephalogram(EEG) signal data, electromyogram(EMG) signal data, selected frequency and signal strength value. CONSTITUTION: Electrodes area arranged on the head 10 of the reagent, and a signal provided by an electrode array module 12 is transmitted to an amplifier system 14. Amplifier EEG, EMG and EOG analog signals are provided to an analog multiplexer included in a conversion module 15 and next transmitted to an analog/digital converter. A digitized sample provided by the conversion module 15 is sent to a signal processing part 16. Ordinarily, analysis is performed from an operator by various kinds of references in order to determine sleeps and awakenings on various kinds of stages shown in the data provided form the head 10 of the testee by a test for several hours. A display and input module 17 is communicated with the signal processing part 16 and the operator can receive a response and an inquiry from a signal analytic system on the display of the module 17. |
