摘要
CRT电磁泄漏问题越来越得到人们的重视,泄漏信号的分析成为其中极其重要的一环。小波分析具有良好的局部化性质,可以进行时频域的多分辨率分析。将小波分析用于CRT电磁泄漏的分析中,对泄漏信号进行了滤波降噪处理,并对行同步信息进行了提取。
People are paying more and more attention to CRT electromagnetic leakage and the analysis of leakage signal becomes one of the most important factors. Wavelet analysis has good localization and can be used in multi - resolution analysis of time domain and frequency domain. In this paper wavelet analysis is used in the analysis of filter and noise reduction in CRT electromagnetic leakage, finally the information of row synchronization is picked up.
