Xue Yang, Ye Xu, Anran Li · 2023
This article introduces the basic principles of wavelet analysis and proposes a signal denoising method based on wavelet analysis to address the problem of signal noise in practical engineering. The system is also designed. This method mainly utilizes wavelet transform to decompose and reconstruct the signal, processes it by calculating the threshold, and finally reconstructs the signal. This method has been used to denoise vibration signals in practical engineering, and the results show that it can effectively preserve useful information in the signal while ensuring the denoising effect. It overcomes the shortcomings of traditional algorithms in dealing with high-frequency noise and has good engineering application value.
