FIELD: computer engineering. SUBSTANCE: system has cable with set of electrodes, protection elements, controllable switches, test signal forming unit, and difference signal forming unit. System also includes series-connected differential amplifiers and filters, commutator, analog-to-digital converter, microcomputer, galvanic decoupling unit, interface unit, and personal computer. Circuit forming the signal of sinphase component suppression consists of series-connected amplifier, protection element and respective electrode. Electrodes are connected to inputs of difference signal forming unit through protection elements. Unit outputs are connected to unit inputs through contacts of switches. Unit outputs are connected to commutator inputs through amplifiers and filters. Commutator output is connected to analog-to-digital converter input. Outputs of analog-to-digital converter are connected to digit inputs of microcomputer parallel port. Output of microcomputer sequential asynchronous port is connected to input of sequential port of personal computer through galvanic decoupling unit and interface unit. Above-indicated system provides for average speed of information input into computer commensurable with maximum speed of information input through sequential asynchronous port. Information input and processing are free of failures. EFFECT: extended functional capabilities. 1 dwg
