| Abstract: | Based on the detailed presentation of the features of acoustic emission signal and the theory of wavelet transform, the applications of the wavelet transform, that has the ability of localized analysis in both time and frequency domains at the same time, to feature extraction, time and frequency analysis and denoising are described. |
| Keywords: | Acoustic emission testing Wavelet transform Signal processing |
