Modulated Broadband Mode Decomposition for the Feature Extraction of Double Pulse Metal Inert Gas Welding

A lot of adaptive signal decomposition methods have been applied for nonstationary DPMIG electrical signals as they are always affected by noise. Recently, to solve the problems of former methods caused by the Gibbs phenomenon and the calculation of extremas when dealing with broadband electrical si...
