An analysis of average response computations based upon aperiodic stimuli.

Average response computation has come to be a widely-used method for the study of evoked potentials recorded from the central nervous system. A mathematical analysis of the mean and variance of the average response computation is presented here. It is shown that an average response computation based upon periodic stimuli will not effectively reduce certain forms of neuroelectric interference. It is further shown that if the stimuli are suitably aperiodic, then the interference can be suppressed.
