Xp. Zheng et al., SIMULTANEOUS APPLICATION OF SPLINE WAVELET AND RIEMANN-LIOUVILLE TRANSFORM FILTRATION IN ELECTROANALYTICAL CHEMISTRY, Analytical communications, 35(2), 1998, pp. 57-59
The spline wavelet can be applied to the processing of signals. It is
particularly appropriate for processing nonstationary signal noise. Ri
emann-Liouville transform (RLT) filtration can be used to remove extra
neous currents from faradaic current, but it is not suitable for filte
ring random noise. Spline wavelet and RLT filtration are combined for
the first time to filter random noise as well as extraneous currents.
Signals with a signal-to-noise ratio of 0.8 can be filtered. Results o
f processing experimental data are satisfactory.
