Noise Reduction of Welding Crack AE Signal Based on EMD and Wavelet Packet
The acoustic emission (AE) signal collected by a sensor in the welding process has an overlapping frequency band and weak characteristics under a complex noise background. It is difficult for the wavelet noise reduction method, with single basis function, to effectively match the different character...
