【Abstract】 In this paper,the wavelet multiresolution signal decomposition was successfully applied to the filtering of high frequency noise in chemiluminescence spectra.The spectra signal to noise ratio was greatly improved while the noise was suppressed effectively.The effect of wavelet basis and time of decomposition are also discussed.It is shown that the wavelet analyses have many advantages in processing of discrete signals.更多还原
