Abstract
A new electric comparator circuit, in particular for electronic calculators, characterized in that it essentially comprises an emitter of electromagnetic vibrations, possibly acoustic, joined to two input terminals on which the control voltages to be compared are applied in opposition, said transmitter being capable of of emitting a radiation when it is subjected to a potential difference at least equal to a predetermined value and a receiver connected to two output terminals, that is to say of use, sensitive to radiations of the emitter and whose electrical resistance decreases considerably when subjected to radiations of the emitter, thus making an electrical connection between the terminals of the circuit of use.
