| Abstract: | In many computer control systems, the monitored signals are unavoidably contaminated by noise. Many signal process techniques can be used to increase the signal to noise ratio. In this paper, a wavelet noise reduction approach and different threshold selecting methods are studied. A series of simulating results by using MATLAB are given. |
