Application of Wavelet Analysis in Metal Magnetic Memory Testing Technology
Ren Qian · Ordnance Industry Automation · 2008
Signals of metal magnetic memory(MMM) is analyzed by using noise reduction,data compression and abnormal signal detection based on theoretics and arithmetic of wavelet analysis. The characteristic parameters are abstracted. Noise reduction of multi-resolution analysis of wavelet transform,data compression of MMM based on one-dimensional wavelet transform and abnormal signal detection of MMM based on wavelet analysis are involved. The conclusion of theoretics and experiments can estimate exactly for MMM signal.
