Wavelet Theory And Recent Advances In the Field of Signal Processing For Acoustic Emission (AE)
The genesis, development and recent advances of the wavelet analysis theory were introduced in this paper. Wavelet analysis method was derived from Fourier analysis theory. The structure and result analysis of wavelet basis are dependent on Fourier analysis. Wavelet analysis can be used to any occasion where Fourier analysis is conventionally adopted. Wavelet analysis takes advantage over Fourier analysis and has undergone spiral-rising development. Meanwhile, the two methods can supplement each other. Besides, the application of wavelet analysis in signal processing for acoustic emission (AE) was dealt with as well. Some deficiencies on wavelet analysis at present were pointed out, and the corresponding tendency in the future development was prospected.
