本文研究快速富里叶变换技术对常规脉冲极谱(NPP)和差分脉冲极谱(DPP)实验数据的滤波处理。对照了迭代数字滤波和七点三次多项式均合平滑,表明 FFT 滤波效果甚佳。此外,还对其优点和注意事项进行了讨论。
In this paper, the fast Fourier transform technique is applied to the filtering of conventional pulsed polarographic (NPP) and differential pulse polarographic (DPP) experimental data. The control iterative digital filtering and the polynomial of the 7.3 degree polynomial all smoothed, indicating that the FFT filtering effect is very good. In addition, the advantages and considerations are also discussed.
