Command protocol for circuits used for receiving microwave signals and device implementing the protocol

摘要

The invention relates to a command protocol for circuits used for receiving microwave signals as well as to a device implementing this protocol. In order to select one or more microwave signals from among the signals which it receives, the reception device comprises switching circuits. The switching circuits are commanded by command signals. According to the invention, a switching circuit command signal consists of at least two sinusoidal signals generated according to the principle of voice-frequency dialling. The invention applies more particularly to the reception of signals from telecommunication and/or telebroadcast satellites.
