| Abstract: | Purpose：We do it to remove the clutters and overcome the limitations on resolution of STFT method, head to improve the accuracy and timeliness on heart sound analysis. Method：We recommend CWT filtering theory ,then design algorithm based on the theory and use the way of LabVIEW2011 to program for achieving in the application. Result： We have successfully used the CWT filtering method to carry out clutters. Conclusion： Using the method described above can achieve the goal for the optimization of the heart sound signal processing. |
