| Abstract: | This paper briefly reviews the main research contents of the separation and extraction of mechanical fault vibration signals. Several methods and their applications for the separation and extraction of periodic and impulse response signals are discussed. These methods mainly include adaptive filtering, time-frequency filtering, adaptive signal decomposition and blind signal separation. Some prospects about their development trend are presented. |
