脑电遥测技术的研究

The study of EEG telemetry technology

本文提出了一种新型的脑电遥测技术。利用两个调频信道、通过公用电话线进行信号传输：其中一个调频信道采用时分多路复用的方法实时传输多导联脑电信号；另一个调频信道则同步发送状态参数以供接收方进行数据标识或同步处理。该技术能涵盖任何常规临床诊断的实际需要，并且波形传输质量好、失真度小、无明显噪声污染、无基漂，具有较高的应用价值。

This Paper brings forward a new technology of EEG Telemetry．Using two FDM channels the signals can be transmitted through public telephone lines the EEG signals are transmitted by TDM technology in one channel the parameters are transmitted to the receiver for identification of data or synchronization in the other channel synchronously． This technology can satisfy almost any routine clinic needs and also the quality of transmission is nearly perfect the distortion is little distinct noise pollution and shift of base－line do not exist which is valuable in medical application．
