The Realization of Time-Varying Filtering for Physiological Signals

Abstract:

Purpose: We do it to eliminate the influence of clutters to the whole of system, improve identification for waveform, and then make ready for the next analysis. Method: We recommend time-varying filtering theory, make this theory as the basis to delimit experimental indicators for the specific requirements, then used LabVIEW2011`s paramount means packet for programming. Result: We have successfully used the varying filtering method to carry out clutters, improved the accuracy of the signal waveforms. Conclusion: Using the method described above can achieve the goal for the optimization on the heart sound signal processing, and also provide the reliable indemnification for analysis from the root.
