| Abstract: | The basic theory and algorithm of wavelet and wavelet packet were introduced. Methods for eliminating noise signal in visible adsorption spectra of fruit juice sample using wavelet and wavelet packet were investigated. The experimental results of two ways were analysed and estimated by one demensional function in Maltal 6.0 wavelet toolbox and our programming. The results were satisfied that the wavelet and wavelet packet analysis have advantage in denoise signal process of spectra and can be used well in the fruit juice quality measurement. |
