摘 要: 采用二进尺度小波变换的Mallat算法 ,应用Daubechics小波 ,讨论了小波分析理论在电子电器设备电磁兼容研究中的应用 .从实验仿真的结果表明 ,由于小波变换具有多分辨率特性 ,能迅速有效地提取某一频率的信号 。 Mallat's algorithm of dyadic wavelet and Daubechies wavelet being used, a new method for the test and diagnosis of Electromagnetic Compatibility based on wavelet transform is put forward. The result of computer simulation of EMI signal is presented. Because the feature of multi-scales the wavelet transform can extract EMI signal in some frequency quickly and efficiently, this method proves more suitable for research on Electromagnetic Compatibility.
