Abstract

Perfeccionamientos en aparatos de control automático de frecuencia del tipo de aparatos de discriminación de frecuencia para detectar la desviación de frecuencia de una señal de entrada a partir de una frecuencia de referencia predeterminada, caracterizados porque comprenden un primer circuito sintonizado que tiene una frecuencia resonante que es menor que la frecuencia de referencia predeterminada; un segundo circuito sintonizado que tiene una frecuencia resonante que es mayor que la frecuencia de referencia predeterminada; un primer dispositivo de amplificación acoplado en serie con el primer circuito sintonizado a través de dos terminales de una fuente de alimentación y que responde a la señal de entrada para alimentar una primera corriente de señal al primer circuito sintonizado; un segundo dispositivo de amplificación acoplado en serie con el segundo circuito sintonizado a través de los dos terminales de una fuente de alimentación y que responde a la señal de entrada para alimentar unasegunda corriente de señal de la misma fase que la primera corriente de señal al segundo circuito sintonizado, y medios para detectar las magnitudes de los voltajes de la señal desarrollado en el primer y segundo terminales con los circuitos sintonizados en respuesta a las corrientes de señal de igual fase.
