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.
本文提供了一个简单的调制解调器系统的电路图和示波器记录样本，该系统可使用家用磁带录音机记录低频生物电现象。该系统经济实惠且易于使用。其中几个系统已在常规实验室应用中成功使用了一年多。
