摘要:
在采集心音信号过程中，难免要引入噪声，这些噪声影响到心音的分析结果。由于心音信号的非平稳性，普通的滤波方法在滤去噪声的同时，会丢失部分心音成分。文中提出了一种新的基于小波变换的自适应滤波方法，该方法能够有效抑制噪声，经实例验证，取得了满意的结果
Abstract:
In process of recording heart sound, it is inevitable that many kinds of noise will be merged in the main signal, The noise will produce the disadvantage factor and influence the results. Heart sound is a highly nonstationary signal, the common way will throw off the noise, but the part signal will be thrown off. A new adaptive filter based on wavelet transform is described. Tests prove that this method makes effective denoising. And the result is better
