摘要
The vibration signals of a system always carry the dynamic information of the system. These signals are very useful for the feature extraction and fault diagnosis. However, in many cases, because these signals have very low signal-to-ratio (SNR), it is difficult to extract feature components and the application of information. Therefore, A de-noising method based on wavelet analysis is applied to feature extraction for electrical signals, and the feature sound is extracted successfully.
