摘　　要：本文介绍了一种新的脑电信号有线传输技术 :经公共电话网络、通过一个调频信道、利用时分多路复用方式可同步传输多达 2 0导联的脑电信号 ;通过另一个调频信道 ,接收方还能实时获知受测试者的当前意识状态以及实现收发双方的同步。经在此基础上开发的脑电遥测系统的使用验证 :该技术能涵盖大部分临床诊断的实际需要、并且信号的传输质量较好、失真度小、无明显噪声污染、无基漂。A kind of EEG(electroencephalogram) tele transmission technology is introduced in this paper, up to 20 leads of signals can be transmitted synchronously using TDM technology in one FM channel through public telephone networks; on the other hand, current potential evocation method and commands of synchronization between transmitter and receiver are also transmitted through the other FM channel simultaneously. The EEG telemetry system, which is developed on the basis of this transmission technology, has shown that this cable transmission technology can satisfy almost all clinic needs. The quality of tele transmission is nearly perfect, and distortion of signals, noise pollution and shift of base lines nearly do not exist.
