A circuit is described for automatic on-line real-time elimination of electrode-pop artifact from EEG recordings, which can occur occasionally from a sudden change in the dc contact potential at an electrode. The circuit, which functions irrespective of polarity and amplitude (over a wide range) of the artifact, is intended primarily for eliminating this artifact from EEG's for computer analysis, from which spurious results can otherwise emerge. Examples of operation of the circuit are included.
