Abstract

L'invention concerne un système de traitement électromagnétique d'une onde d'entrée comprenant les étapes consistant à recevoir un signal modifié dérivé d'au moins deux signaux représentant l'onde d'entrée quand ils sont combinés; et à réguler le signal modifié au moyen d'un signal numérique renfermant au moins une caractéristique des deux signaux. Des modes de réalisation de l'invention peuvent mettre en oeuvre des signaux en phase et en phase quadrivalente, la partie d'amplitude des signaux pouvant être utilisée pour réguler le signal modifié. Celui-ci peut être créé par modulation d'une caractéristique des signaux I et Q, telle que leur signe, au moyen d'une onde porteuse RF ou d'une autre fréquence.
