| Abstract: | One-dimentional wavelet packet analytic function in MATLAB wavelet toobox is applied to eliminate noises in signal by acuiescent and variational theshold.In this paper,eliminate noises in visile spectroscope as an example,estimate the results of eliminating noises by two ways.The results are satisfactory.So,it is proved that wavelet packet analysis is doable in signal denoise. |
