【摘要】 小波多分辨率分解能够将信号在不同的尺度上展开，因而具有对信号按频带进行处理的能力，这对于分析特定频段上信号的细节，建立表征识别故障信号的特征以及清除信号的干扰与噪声等方面具有十分重要的意义。本文给出了信号多分辨率分析在信号消噪方面的具体应用实例。更多还原

【Abstract】 The mulitresolution analysis of wavelet can decomposite signal on different Scales.So it has the ability of processing for signal in frequency-band,which is very useful to analysis the details of signal on a given frequency-band,to build up the identification features of signal and to cancel the signal noise.This paper gives out the examples of the multiresolution analysis in signal canceling noise.更多还原
