Amplitude modulator-demodulator system for recording electroencephalographic signals with a standard 1/4 inch magnetic tape deck. 1975

M W Luttges, and R A Gerren, and D E Groswald, and W Bank

Circuit diagrams and a sample oscilloscopic tracings are provided for a simple modulator-demodulator system which permits the recording of low frequency bioelectric phenomena with an entertainment type tape recorder. The system is economical and easy to use. Several of the systems have been used successfully in routine laboratory applications for more than a year.
