Research on Weak Signals Based on 2D-WT Method

Abstract:

Objective: What we do is intended to analyze weak signal more conveniently and easily. Method: We recommend 2D-WT method, then designed the programs by the way of LabVIEW2011 developers paramount toolkit, at last we realized to change one-dimensional heart sound signals into the form of 2D synthesized intensity maps for easily analyzing. Results: We have successfully used programs to realize intuitional analysis on the signals. Conclusion: Using the method described above can realize analysis on heart sound signals.
