ABSTRACT:
A coaxial cable switching circuit includes a differential comparator connected to a cable to be switched, for receiving a switching pulse therefrom. The output of the differential comparator is connected to a pulse width discriminating circuit which in turn controls a coaxial switch enabling selective interconnection of the coaxial cable with a pair of further coaxial cables. The pulse switching circuit may include a latching device, enabling the alternate connection of the further coaxial cables to the cable to which the switching pulse is applied.
