摘要：

本文介绍了体表胃电的提取及胃慢波节律的自动检测技术。体表胃电提取时，采用本文给出的胃电放大器的设计方法及信号叠加平均技术，获得了较好的信号噪声比

A method for cutaneous recording of EGG and an antomatic detecting technique for fundamental frequency of gastric electrical control activity (ECA) are presented in this paper.By using a method of desigh of EGG amplifier and a technique of signal averaging,higher signal to noise ratios of EGG were obtained during recording.
