摘要
为了解决光电流宽输入范围问题,针对现有脉搏信号采集系统不足,设计了一款基于ADS125H02自适应脉搏信号采集系统,具有采集精度高、噪声小、抗干扰、宽输入范围、集成度高等特点。该系统测量范围可达±10 V,精度为0.009μV。实验测试表明,该系统设计能较好地提取微弱的脉搏信号,具有实用性。
In order to solve the problem of wide input range of photocurrent,aiming at the shortage of existing pulse signal acquisition system,an adaptive pulse signal acquisition system based on ADS125H02 is designed,which has high collection accuracy,low noise,anti-interference,wide input range,high integration,etc.The measurement range of the system can reach±10 V,and the accuracy is 0.009μV.Experimental tests show that the design of the system can extract weak pulse signals,and has good practicality.
