摘要
将Ｆｏｕｒｉｅｒ变换技术应用于示波信号的处理，提出了高次微分示波图的频谱分析和高次谐波示波计时电位法。用于示波图中背景和噪音的扣除及定量测试，获得满意的结果。
Using Fourier transform technique to deduct background and noise on dE/dt t curve,two new electroanalytical methods,high order harmonic oscillographic chronopotentiometry and frequency spectrum analysis of high order differential oscillogram,are presented.These methods are applied to deduction of background and noise on oscillogram as well as analytical determination with satisfactory results.
