| Abstract: | The concept of wavelet transformation is introduced. Makes use of the changing focal distance and location characteristic of wavelet transformation, multiresolution analysis steel wire rope testing signal of leak magnetic field. Wavelet transformation is used to make time - frequency analysis of the signal from the broken wires in a steel rope. As a result express that the method has the excellent characteristic for singular signal detection and localization analysis. Wavelet transformation can focuses detail of signal and keep with time - frequency analysis for sudden signal. |
