| Abstract: | Reducing the noise interference effectively is very important in the accurate analysis of the spectral data.On the base of the wavelet analysis and the median filtering technology a combined filter design scheme is described in this paper.The simulation spectrum data and the measured spectrum data captured with spectrum instrument are used to check the validity of this method.Experiment results show that not only the pulse noise and white Gaussian noise can be effectively reduced,but also it remains the details information in the spectrum after the processing finished with the method of this paper. |
