A simplified circuit for stimulus artifact suppression.
This note describes a simple electronic method of eliminating time-locked stimulus artifacts from recordings of cerebral evoked potentials. The hardware required for a 16-channel battery-powered suppressor system costs less than $80. The complete circuit can be fabricated from readily available components on a single 6.5x4.5 in., 44-pin circuit board.
