Methods The envelope extraction of heart sounds based on Hilbert-Huang Transform was given.
方法本文提出了利用希尔伯特-黄变换对心音信号进行包络提取的方法。
With the frequency band separation characteristic of wavelet and wavelet transform characteristic of noise, the accuracy of envelope extraction is improved.
在实时信号分析中,离散小波变换在DSP上的有效应用受到了特别的关注,介绍了Mallat快速小波变换算法,通过与常用小波基相对应的正交镜像滤波器组,实现了对信号的快速小波分解;利用小波的频带分离特性和噪声的小波变换特性,提高了信号包络提取的精度。
