摘要
本文利用小波分析的多分辨特性,对叠加强噪声后的电磁干扰信号进行了研究,并准确地还原出了原始的信号,为进一步抑制干扰源提供了理论依据,也为分析矿井电磁干扰信号提供了一个有效的途径。
In this paper, the multi-resolution wavelet analysis is used to study the electromagnetic interference signal with superposed strong noise and restore the original signal accurately, thus providing the theoretical basis for further restraining interference source and an effective way to study the electromagnetic interference signal in the coal mine.
