一、概述脑电波(EEG)是一种随机性电生理信号,主观目测分析比较困难。随着电子技术的发展,现在已经研制出多种多样分析仪器,如:频谱分析仪、分波段的平均频谱仪、相关分析仪、求导分析仪、特定尖峰信号检测仪以及利用电子计算机枝术进行分析处理等多种装置。其中发展最早、使用方便,直到目前国内外还在广泛流行的是平均频谱分析仪,这种仪器是瓦尔特(Walter)于1943年首先研制成功的。尽管电子线路已发展到组件化阶段,仪器的质量有了很大提高,但其组成原理方框图没有重大改变,还是所谓瓦尔特型式。根据我部生理研究和医学监测任务的需要,
First, an overview EEG (EEG) is a random electrophysiological signal, the subjective visual analysis is more difficult. With the development of electronic technology, a great variety of analytical instruments have been developed, such as spectrum analyzer, sub-band average spectrum analyzer, correlation analyzer, derivation analyzer, specific peak signal detector and the use of computer technology Analytical processing and other devices. One of the earliest development, easy to use, until now is still widely popular at home and abroad is the average spectrum analyzer, this instrument is Walter (Walter) was first developed in 1943. Although the electronic circuit has been developed to the component phase, the quality of the instrument has been greatly improved, but the block diagram of the composition of the principle of no major changes, or the so-called Walter type. According to my department’s physiological research and medical monitoring mission needs,
