Aiming at the extraction of failure character signal for early acoustic emission (AE) signals, a method to combine lifting wavelet packet with spectrum zoom technology is developed. Using lifting wavelet packet de-noising method, not only filters the

To solve the problem of difficult to extract fault features from the early weak AE signal, a method combining lifting wavelet with EMD is proposed. Firstly, the lifting wavelet is used to de-noise the AE signal, then the signal after de-noising is de
