摘要
介绍一种ＩＢＭ－ＰＣ系列微机生理信号采集、处理系统。该系统信号采集卡集程控放大、脉冲甄别、Ａ／Ｄ、Ｄ／Ａ等电路于一体，可满足各种生理信号的采集需要。采集信号时可长时间显示，动态观察。采样后，按需要给出各种图表与结果。部分处理方法采用独特数学模型，使结果更加精确。
A system based on IBM-PC series microcomputer is reported.It is developed
for collecting,analysing and processing physiological signals.The collecting card of the system
consists of aprogram-controlled ampllfier,an impulse detector,an A / D circuit and 4 D / A
circuits.It canbe used for collecting various sorts of physio logical signals.The signal can be
displayedcontinuously and observed dynamically while being collected.After sampling,various
sorts of di-agrams and results can be provided aecording to the needs.Besides,special
mathematical modelsare adopted in some processing methods to make the results more
precise.
