摘要
The use of the continuous and discrete wavelet analysis for investigation and filtering of acoustic signals and fields is considered. Special attention is paid to the application of wavelet filtering for improving the quality of the visualization of flaws. Wavelet contour plots, a new method for representing information, are introduced. This technique simplifies the determination of conventional dimensions of flaws.
