Wavelet packet decomposition technology has been used to analyze the fault signals in ball mill, a kind of fault feature extracting method based on Wavelet packets decomposition is put forward.
不同状态下相同频段信号的小波系数也不相同，因此可用不同频段信号的小波包系数来表征不同信号的特征。依据以上分析给出了一种基于小波包分解的故障特征信息提取方法。
The interpolatory wavelet packets constructed by our method can provide a finer decomposition for the cardinal interpolation space and give a better localization for an adaptive interpolation.
按照这个方法构造的插值小波包能对基插值空间提供较为精细的分解，因而对自适应的插值给出较好的局部化。
