摘要
该文简要介绍了脉搏信号的时域特征,在此基础上针对阈值法存在的缺陷,重点分析了用极值法提取脉象信号特征点的思想,发现极值法可以较准确地提取出脉搏信号的时域特征,为下一步脉象的判别奠定基础。
In this paper,we briefly introduces the timedomain characteristics of the pulse signal.On this ba sis,we focused on the idea of the extremum method in extracting the pulse signal feature points,aiming at the disadvantages of the threshold value method.Finally,we found that the extremum method would extract the time domain characteristics of pulse signal accurately,and laid a solid foundation for differentiating each type of pulse.
