Lj. Bao et al., COMPARATIVE-STUDY ON SIGNAL-PROCESSING IN ANALYTICAL-CHEMISTRY BY FOURIER AND WAVELET TRANSFORMS, Huaxue xuebao, 55(9), 1997, pp. 907-914
The Wavelet transform is a new numerical algorithm in processing analy
tical chemistry data. It is an advance of Fourier transform method. In
this paper, we have compared the properties, algorithm and the result
s of processing data of Fourier and Wavelet transforms. The B - spline
Wavelet's algorithm have a lot of advantages such,high-speed,low memo
ry requirement and high-precision and not requiring data preprocessing
so on. Especially, it is satisfying to process the high noise data ev
en the signal-to-noise ratio is as low as 0.2.
