| Abstract: | The properties of fault signals of motors are studied using dyadic wavelets transform in this paper,which can be treated as signals with sigularities.The method of removing white noises is presented by using the difference between the wavelets transforms of white noises and those of fault signals of motors in this paper."Denoised" signals can be reconstructed by using this practical algorithm. |

| Keywords: | singularity white noise / dyadic wavelets |
