Paper Abstract

Based on the different characteristics between signal and noise, this paper studied wavelet denoise method on ECNT (Eddy Current Nondestructive Detecting), authors found regularity of noise and nondefect signals arising from the support plate used to hold the tubes, and introduced a new method removing the support plate disturbance using wavelet multi-scaling edge detecting technology. The result shows that this method is better than the current one in the respect of hardware cost.
