Neng Li · Microcomputer & its Applications · 2010
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.
