Abstract
a. Détecteur de phase. b. Détecteur caractérisé par un premier moyen de couplage pour coupler le premier et le second filtres passe-haut, en série entre les deux bornes d'entrée, un second moyen de couplage pour coupler les points de jonction des condensateurs et des résistances du premier et du second filtres passe-haut, sur les bornes d'entrée de l'amplificateur différentiel, un générateur de signaux en quadrature de phase recevant le signal d'entrée de référence du second moyen de couplage de façon à créer un signal en quadrature de phase en réponse à la fréquence du signal d'entrée de référence, et un multiplicateur recevant chacun des signaux de sortie de l'amplificateur différentiel et du générateur de signaux en quadrature de phase, pour créer un signal de sortie proportionnel à la différence de phase entre les signaux.
