摘要
脑电信号在外围设备采样后,由计算机通过软件系统以波形图形式进行实时播放.本文以脑电波监护与分析的系统给出计算机技术在工程领域的应用实例.首先介绍涉及的脑电生物及数字信号处理技术的背景知识,然后讨论软件体系结构、子系统划分及功能模块,包括脑电信号的监护、数字滤波器及信号分析,并以数据采集、滤波与分析算法为重点.
Electroencephalogram （EEG） signals are collected by peripheral equipments before being sent to computer. The computer shows the EEG waves in real time manner meanwhile digital signal processing techniques are used to analyze them. An EEG monitor and analysis system is presented. Some background knowledge about EEG and digital signal processing techniques are introduced and then the design and implementation of this software system is given. The system architecture and function modules （the EEG monitor, digital filter and analysis） are studied.
