Abstract: A system and method of identifying and removing artifact from radio frequenc y noise from biopotentials identifies epochs contaminated with radio frequency noise. Contaminated epochs are then replaced with recent uncontaminated epoc hs stored in a buffer, depending on the current level of artifact and the availability of suitable data. Discontinuities arising at the beginning of t he replaced epochs are smoothed by means of a windowing function.
