| Abstract: | Eddy current testing technology is often used in the on-line plate surface crack detection but the output signal is relatively weak and terribly interfered. In this paper, the method of wavelet transform is applied to analyze testing signals. The noise of the signal can be removed and the eigenValue can be strengthened. |
