摘要
本文简述了小波分析理论及基于小波变换的去噪方法 ,针对氮爆式液压破碎锤测量信号非平稳时变特点 ,对其进行小波分析处理。结果表明 。
The paper describes the theory of wavelet analysis and the de-noising methods based on wavelet transform briefly.With a view to non-stationary transient characteristic of the signal measured on Nitrogen-Inflating hydraulic impact hammer.This paper uses the discrete wavelet transform to processe them.The results have indicated that the de-noised signal is easy to observe and analyse.
