Notes on EEG resampling by natural cubic spline interpolation

Abstract

Resampling of digitized electroencephalographic data allows changing the sampling rate with minimal distortion of the signal. Useful applications of the procedure include compatibility among diverse hardware and software and the customization of data analysis. The natural cubic spline interpolation procedure is introduced in a discursive fashion. A formal presentation is provided in the appendix. © 2002 by The Haworth Press, Inc. All rights reserved.
