Abstract

Un oscilador con modulación de ángulo con un bucle sincronizado en fase consistente de un oscilador controlado a tensión, un divisor, un discriminador de fase, un filtro de bucle y un oscilador de referencia que actúa a través de un divisor fijo sobre el discriminador de fase con una señal de referencia, caracterizado porque la señal de referencia subdividida (U2) se modula por la señal de modulación (ul).
