基于小波多分辨分析的振动数据压缩研究

Research on Wavelet Multiresolution Analysis Based Vibration Signal Compress

小波多分辨分析能够将信号在不同的尺度上展开 ,因而具有对信号按不同频带进行处理的能力 ,这就使小波分析应用于数据压缩成为可能 ,给出了小波分析应用于旋转机械振动信号压缩的实例。

The signal can be decomposed on different scales by the wavelet multiresolution theory, so the signal can be studied on different frequency bands. This made it possible to apply the wavelet analysis to data compression. The paper gives an example of vibration signal compression by wavelet analysis in area of rotating machinery.
