Abstract

L'invention concerne les circuits de modulation de phase. Un modulateur de phase réalise une modulation de phase conformément à la fonction arc cosinus d'un signal modulant, à l'aide d'un circuit 10 qui calcule la fonction arc tangente hyperbolique du signal d'entrée d'un circuit 20 qui module un signal porteur avec une somme en quadrature de deux signaux exponentiels liés au signal de sortie du circuit 10, et d'un circuit 30 qui effectue une limitation abrupte, et un filtrage du signal modulé. Application aux amplificateurs interférométriques de signaux de haute fréquence modulés en amplitude.
