title: [4-channel electroencephalographic amplifier with integrated microcircuits].
abstract: To conduct electroencephalographic investigations of stationary and moving objects a small-sized 4-channel amplifier built with integrated microcircuits has been developed. Each channel includes a pre-amplifier, main amplifier, calibrator, high and low frequency filters and a power pack. The adoption of integrated microcircuits enables it to locate the pre-amplifiers directly on the object of investigations. The device is highly sensitive and secures a greater degree of noise-protection.
