Title (EN) METHOD AND APPARATUS FOR SUPERVISING AN AUDIO CIRCUIT WITH CONTINUOUS AUDIO
(FR) PROCEDE ET DISPOSITIF DESTINES A CONTROLER UN CIRCUIT AUDIO EN MODE AUDIO CONTINU
Abstract: front page image
(EN)An apparatus (100) and method for monitoring an audio circuit while the audio circuit is simultaneously generating an audio signal. Specifically, an AC audio signal and DC current source supervision signal are superimposed over a speaker circuit. These signals are superimposed at the junction (145) where a first DC filter (14) and a first AC filter (130) are connected.
(FR)L'invention concerne un dispositif (100) et un procédé destinés à contrôler un circuit audio pendant que ce circuit audio génère simultanément un signal audio. Plus particulièrement, un signal audio alternatif et un signal de contrôle d'une source de courant continu sont superposés sur une ligne de service. Ces signaux sont superposés au niveau de la jonction où un premier filtre à courant continu et un premier filtre à courant alternatif sont connectés.
