Abstract

Recently, the interest and the importance of the signal monitoring and recording during sleep is increasing. Conventional paper based recording systems are being replaced by digital type and polysomnographic system. We developed special digital signal processor system for the polysomnographic recording. This system consists of digital signal processing part and PC interface part for user's convenience. This system includes two digital filters, one fur low pass filtering of high frequency noise and the other for notch filtering of 60Hz AC noise. This system can be used for the efficient and convenient measurement of polysomnographic signals and also can be developed for the portable use.
