Abstract

Improvements in the apparatus for feeding the single sideband receivers comprising a waiting apparatus characterized in that it comprises: a device for the detection of speech signals in the presence of noise; an electronic clock controlled by the detection device, the period of which consists of a short time during which the receiver is normally powered and of a long time during which the receiver is fed in a reduced form, the long time and the short time in a constant ratio, and binary-type switching means operated by the clock and controlling the power of the receiver to cause said power to pass to the clock's own frequency at the normal progress state and the reduced progress state, the clock remaining, and consequently said switching means, in the normal progress state whenever there is detection of conversation signals.
