A simple noise clipping circuit for neurophysiological audio monitors. 1983

J Millar, and T G Barnett

A very simple circuit is described which removes the low amplitude components of audio frequency signals, leaving the positive and negative peaks superimposed on a flat baseline. The clipping is symmetrical and adjustable in gain. Thus the baseline noise in audio monitors used in extracellular single-unit recording can be attenuated. This enhances the aural discrimination of single units and reduces aural fatigue.
