Patent FR-2630602-A1 (FR)
Title: Appareil de reception de signaux modules en amplitude et de signaux modules en frequence
Inventor: OKANOBU TAIWA
IPC: H03D7/18
Filed: 1989-04-26
Abstract: Un signal d'information modulé reçu est converti en un signal de fréquence intermédiaire à partir duquel l'information de modulation peut être extraite par délivrance du signal d'information modulé à deux mélangeurs 32, 33 recevant des signaux d'oscillation locale de même fréquence, mais déphasés l'un par rapport à l'autre. Les signaux de sortie produits par les mélangeurs sont délivrés par l'intermédiaire de circuits déphaseurs 34, 35 qui confèrent des déphasages prédéterminés à ces signaux de sortie si bien que les composantes de signaux d'image présentes dans certains, respectifs, des signaux de sortie des mélangeurs sont déphasées de manière à être en opposion de phase mutuelle. Les signaux de sortie déphasés sont combinés 36, de sorte que les composantes de signaux image en opposition de phase sont sensiblement annulées. Un filtre 51, 61 accordé sur la fréquence intermédiaire est connecté à la sortie du circuit de combinaison afin de laisser passer les signaux de sortie des mélangeurs possédant des fréquences comprises à l'intérieur d'un intervalle prédéterminé de la fréquence intermédiaire.
