Abstract

Ce système de radiodiffusion à modulation de fréquence assure la caractérisation d'émetteur à l'aide d'une sous-porteuse émise en même temps et modulée à deux phases par les signaux de caractérisation d'émetteur. Dans l'émetteur, la sous-porteuse est couplée au signal pilote stéréo, tandis que dans le récepteur, le signal non modulé, indispensable pour la détection du signal de caractérisation d'émetteur, est déduit du signal pilote stéréo reçu. Application aux radiorécepteurs.This frequency-modulated broadcasting system provides transmitter characterization using a simultaneously transmitted subcarrier and two-phase modulated by the transmitter characterization signals. In the transmitter, the sub-carrier is coupled to the stereo pilot signal, while in the receiver, the unmodulated signal, essential for the detection of the transmitter characterization signal, is deduced from the received stereo pilot signal. Application to radioreceptors.
