| Abstract: | The paper studies FFT digital data filtering for pulse polarographic data.The originaldata are modified by translation-rotation operation prior to Fouries transformation,andthe retangular filter function is imposed.The FFT digital data filtering is compared to or-dinary digital filtering and seven-point,cubic least-square smoothing.We find that FFTdigital data filtering is most effective.In addition,advantages and pitfalls are discussed. |
