The Magnetic Memory Examination Signal Processing Based on Wavelet Analysis
This paper presents the wavelet analysis theory applied to processing magnetic memory examination signal. By eliminating noise, checking the irregularity and withdrawing, as well as suppressing frequency sector, the flaw time domain locates accurately and the gradient contrast effect is obvious. It provides a new method for magnetic examination evaluation.
