This paper is a brief introduction to discrete wavelet transform as digital signal-processing technique and the application. The field of discrete wavelet transform (DWT) is an amazingly recent one because itÌ s better than Fourier transfor

利用小波分析 对变压器局部放电信号进行去噪处理 课程作业 效果不错-Transformer using wavelet analysis of partial discharge signal de-noising processing coursework good results

本文介绍了局部放电信号的消噪方法，主要基于改进的小波消噪和序列脉冲分析手段来实现。-This paper presents a de-noising method for partial discharge (PD) online monitoring of transformers. The method is based on an improved wavelet de-noising approach and a pulse-sequence analysis method.
