Abstract : The development of a simple system for the averaging and analysis of repeated electrical signals is described. Samples are accumulated on a closed loop of magnetic tape, using a special form of pulse-interval modulation, designed also to enable simple circuitry to compute correlations. A low-speed and a highspeed multi-channel model have been developed, with capacities of up to 900 samples per channel. First results with the E.E.G. of human subjects exposed to patt rned visual stimuli are described. (Author)
