| Abstract: | The phase measuring system of the two channel vibrating based on the hardware structure has large measuring errors. By wavelet transform, selecting proper kernel function and scaling factor, the singal to noise ratio of the original waveform with sampling noise can be improved and the peak points of the signal keep unshifted. The results of simulation and experiment were also provided in this paper. |
