Abstract: Smoothing of the digital data for computerized electrochem ical instrument by the piecewise third-order spline function technique is reported.The original digital signals in different noise levels measured from electrochemical experiments have been handled with the method.The results show that the processed digital signal waveforms are less distortion and signal- to-noise ratio enhancement.

Key words: Digital signal, Third-order spline function, Smoothing
