Abstract

L'invention concerne des procédés et appareils permettant une sélectivité et une translation de fréquences, ainsi que leurs applications. Le procédé consiste à filtrer un signal d'entrée et à transposer le signal d'entrée filtré. Les opérations de filtrage et de transposition sont exécutées d'une manière intégrée et unifiée. L'appareil concerné peut être implanté comme circuit intégré (CI). Il peut également contenir un ou plusieurs modules de commande de gain.
