The realization of DWT filtering for heart sound signal based on LabVlEW2011

目的 :为了能对具有不同特点的心音信号实现灵活滤波。方法 :基于DWT理论进行滤波器的设计,引入不同类型的小波和阈值参量进行分析,基于LabVIEW2011进行编程实现设想。结果 :成功利用基于DWT理论设计的滤波器对心音信号滤波。结论:采用上述方法能够实现对于心音信号的滤波处理。

Purpose:We do it to achieve flexible filtering on the heart sound signals with different characteristics.Method:We design it upon the theory of DWT,then analyse by introducing different kinds of wavelets and threshold parameters,at last,we achieve vision by programming with LabVIEW2011.Result:We have successfully realize filtering on singals by using the filter designed on the theory of DWT.Conclusion:Using the method metioned above can realize filtering on heart sounds.
