The disadvantages of traditional filters in processing non-stationary signals are analyzed. The principle and method of wavelet denoising is researched. The mixed programming with LabVIEW and Matlab is studied,the perfect graph program-ming technique of LabVIEW and the strong mathematic function of Matlab were integrated to realize the mathematical modeling and signal image displaying of denoising. Through the filtering processing of vibration impulse signals,the effectiveness of the method in processing the non-stationary signals is proved.
