摘要
小波变换具有时频局部分析特性,己经成为信号处理中的一种重要工具。阐述其基本原理,利用Matlab语言及小波工具箱,选择合适方法、参数及步骤,实现轧制信号的小波消噪,证明消噪效果令人满意。
Wavelet transform has already been an important tool in signal processing, for its property of timerequency localization.Introduced the basic theory, and made use of the Matlab language and its wavelet toolbox , and chose proper methods ,parameters and procedure to implement signal denoiseing of rolling signal. The result was proved and analyzed. The efficiency of the method is satisfying.
