| Abstract: | In this paper, the theory of wavelet transformation in signal noise reduction is introduced, together with the algorithm of signal decomposition and reconstruction. The decomposition and reconstruction functions are employed for noise reduction in the stress and torsion vibration signal process of the main drive axes of rolling mill, with good results obtained. |
