1. An electronic clinic apparatus, comprising in combination:

  • a group of a number of probes positioned in proximity to at least one body surface of a person subjected to a clinic operation;

    a multichannel amplifier for amplifying electrical potential sensed at each of said probes and having an output;

    a multiplexer connected to said amplifier at said output of said amplifier, and having analog outputs;

    converter means connected to said multiplexer for converting said analog outputs of said multiplexer to corresponding digital outputs;

    computer means for processing said corresponding digital outputs of said converter means to produce outputs of said computer means;

    display means for displaying said outputs produced by said computer means; and

    control means provided between said multiplexer and said computer means for successively reading out the sensed potentials at the probes within a variable operating period and for providing a pause period thereafter, said variable operating period being added with said pause period to define a predetermined functional cycle period, said control means intentionally removing improper probe signals including excessively large noise signals and replenishing properly calculated and established imaginary signals in place thereof, said removal and replenishing functions being performed during said pause period.
