| Abstract: | In the signal processing,the noise often degrades the accuracy of the result.Wavelet transforms are multiresolution decompositions that can be used for signal denoising.This paper analyses the idea of wavelet transforms,the process of calculation and the influence of its frequency response,so that wavelet transforms can reduce the noise from the useful signal.The simulation results show that the wavelet transforms are effective. |
