Abstract

Un procédé est fourni pour détecter et réduire loscillation dans un suramplificateur. Ce dernier est configuré pour échantillonner un signal amplifié afin de déterminer si le suramplificateur oscille. De plus, létat de lamplificateur peut être vérifié sur la base des niveaux de signal apparents des signaux amplifiés. Le gain du suramplificateur est ensuite ajusté suivant si le suramplificateur oscille ou comme il est nécessaire pour conserver un gain compatible avec le système dans lequel le suramplificateur fonctionne.
