Abstract

The purpose of the gate circuit is to prevent reception of outside wireless communication services. Behind the intermediate frequency amplifier (3) is a pulse clipper (17) which delivers the line sync pulses each time to an input of a coincidence circuit (19) at one time direct and at another time delayed by a line period. The coincidence circuit delivers a signal to a constant power source (20), which charges a condensor (21) which is continually discharged by means of a second constant power source (22). The voltage arising in the condensor delivers the switching signal for the gate circuit.
