Noise reduction in Magneto-acousto-electrical NDT using analytic wavelet thresholding

摘要：

　　The Noise reduction techniques with wavelet transform are widely used in non-destructive testing and evaluation(NDT&E).In this paper,a new non-destructive testing method referred to as magneto-acousto-electrical NDT was proposed.At the same time,based on fully taking into account the signal features we employ analytic wavelet thresholding method to improve the de-noising performance.The experimental results clearly demonstrate that the proposed de-noising method has good performance in terms of signal-to-noise ratio enhancement.
