Abstract

Comparador de frecuencia y fase totalmente digital está relacionado con el campo de la técnica eléctrónica y de las comunicaciones, y está destinado para proveer una salida que sea proporcional a la diferencia de fase entre dos senales de entrada siempre que esta no sobrepase los límites + pi 3,14 y - pi 3,14 , caso en el cual el circuito mantiene un valor mínimo o máximo hasta que las senales de entrada se sincronicen nuevamente en frecuencia. A diferencia de los esquemas existentes, las magnitudes angulares de entrada y el valor de la salida se expresan en forma totalmente digital, y los bloques utilizados para el procesamiento aritmético de estas magnitudes con circuitos integrados digitales, todo lo cual permite obtener una elevada precisión y una realización más compacta y confiable. La comparación de frecuencia se logra mediante el empleo de una máquina secuencial sincrónica, la cual posee tres estados que se asocian respectivamente a la operación normal y a los dos sentidos posibles de la diferencia de frecuencia entre las senales que se comparan.Fully digital phase and frequency comparator is related to the field of electronic technology and communications, and is intended to provide an output that is proportional to the phase difference between two input signals as long as it does not exceed the + pi limits. 3.14 and - pi 3.14, in which case the circuit maintains a minimum or maximum value until the input signals are again synchronized in frequency. Unlike existing diagrams, the input angular quantities and the output value are expressed in a fully digital form, and the blocks used for the arithmetic processing of these quantities with digital integrated circuits, all of which allow high precision and a more compact and reliable embodiment. Frequency comparison is achieved by using a synchronous sequential machine, which has three states that are respectively associated with normal operation and the two possible directions of the frequency difference between the signals being compared.
