摘要:
采用快速傅里叶变化(FFT)将脉搏信号从时域变换到频域,即将一个复杂的、具有明显周期特征的脉搏波分解成不同频率的谐波。利用Matlab编程,从脉搏波频谱中获取与人体生理病理相应的信息特征,实现了参数提取的程序化,取代了人工读图的过程。
Abstract:
In this paper, we transform the pulse signal from waveform to spectrum by Fast Fourier Transformation (FFT), that is, decomposes a complex pulse wave with obvious characteristics of period into a set of harmonic waves with different frequencies. Then we can obtain some information characteristics corresponding with human physiology and pathology from the pulse spectrum by means of Matlab. So we achieves the aim of extracting parameters programly, which will be instead of the process of artificial reading graphics and has important implications in the future pulse research.
