Title
(EN) PHASE NOISE DETECTOR
(FR) DETECTEUR DE BRUIT DE PHASE
Abstract
(EN) A phase noise detector for a signal having a carrier frequency, comprising a frequency discriminator producing a dispersed signal from the signal and a phase detector means (28) responsive to the carrier frequency in the signal and to a carrier suppressed signal to produce an output signal corresponding to the noise close to the carrier frequency in the signal, the carrier suppressed signal being produced by a carrier suppression means (30) responsive to two input signals, the input signals corresponding to the signal, one of the input signals being the dispersed signal.
(FR) L'invention concerne un détecteur de bruit de phase pour un signal comprenant une fréquence porteuse, constitué d'un discriminateur de fréquences produisant un signal dispersé à partir du signal, et un détecteur de phase (28) sensible à la fréquence porteuse dans le signal et à un signal à porteuse supprimée pour produire un signal de sortie correspondant au bruit proche de la fréquence porteuse dans le signal, le signal à porteuse supprimée étant produit par un moyen de suppression de porteuse (30) sensible à deux signaux d'entrée correspondant au signal, au moins l'un d'entre eux constituant le signal dispersé.
