Abstract
A receiver device for radio emissions, without a carrier wave and with a double sideband, having a derivative path in which a double frequency wave of the carrier is formed by the insertion in said path of a quadratic characteristic rectifier, characterized mainly by that this rectifier feeds a frequency divider of the parametric type known per se, which redoes the carrier wave used in the receiver for the demodulation of the transmitted signals.
