Digital Signals Processing for Computerized Instrument in Electrochemistry(Ⅰ)──Piecewise Third-order Spline Function Method(PTSF)

用分片三次样条函数插值拟合法平滑计算机化的电化学仪器的数字信号，并用于处理不同信噪比的实验数字信号。结果表明，该方法是处理分析仪器数字信号的一个有力工具。

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.
