颈动脉搏动波的谱分析

The Research on Methods for Analysing the Spectrum of CAP Signal

采用周期图法和AR参数模型法分别对颈动脉搏动波进行了功率谱分析.分析结果表明,从脉搏波功率谱的主峰及谱分布稳定性的角度来说,周期图法比AR参数模型法具有更优越的性能.

In this paper, Power spectrum of CAP (carotid pulse) by periodogram and AR model is given, respectively. Comparison of these two methods show that periodogram method is superior to the AR model, in point of the stability of peak and distributing of the power spectrum.
