摘要
介绍了在LabVIEW环境中用声卡采集心音信号,利用MATLAB script节点进行小波去噪的方法。方法充分利用了LabVIEW灵活的图形编程及MATLAB的数学计算能力,实现优势互补,弥补了传统心音检测仪的不足,提高了编程效率,且便于实现,是研究心音信号的有效途径。
This article introduced the method of gathering heart sound signal with the sound card in the LabVIEW environment,and the noise reduction of wavelet by using the pitch point of MATLAB script. This method has made full use of the LabVIEW nimble graph programming and the MATLAB mathematical computation, implemented mutually supplementary in superiority, up for some of the lack of traditional heart sound detector, and thus raised the programming efficiency, is convenient to achieve, and is also an effective way for the studies of heart sound signal.
