摘要
Abstract
There are lots of noise signal in signals of Electromagnetic Non-Destructive Testing(ENDT),which causes enormous difficulties for signal analysis.Wavelet analysis can be focused to different details of a signal,and selecting B-wavelet as wavelet base can further improve the effect of signal analysis.Using it in detection signal de-noising smooth and singularity detection can make the signal smoother and eliminate the jamming signal,avoid wire-breaking misjudgment,and also make the singular point more apparent,effectively improve internal and external wire-breaking recognition and quantitative detection accuracy.The experiment proves that this method is effective.关键词
