Abstract

An improved electronic clinic apparatus includes a group of a number of probes positioned on or above at least one body surface of a person subjected to a clinic operation. It includes further a multichannel amplifier for amplifying electrical potential sensed at each of the probes. A multiplexer is connected with the amplifier at its output and an AD-amplifier is connected with the multiplexer at its output. An electronic computer for treatment of digital outputs from the AD-amplifier is provided. Various and several display units are provided for displaying outputs from the computer. Control means are provided between the multiplexer and the computer for successive read-out of the sensed potentials at the grouped probes and within a variable operating period, and for providing a pause period thereafter. The variable operating period added with the pause period defines a predetermined functional cycle period such as 2 ms. The subject apparatus removes improper probe signal(s) including inhibitingly large noise signals and replenishes properly calculated and established imaginary signals in place thereof. The removal and replenishing job is performed during said pause period.
