Abstract
Un receptor de frecuencia vocal tal como se utiliza en sistemas de telecomunicación caracterizado porque la señal de frecuencia portadora transmitida sobre la línea entrante para fines de señalización o de marcación en disco y alimentadas a la entrada de dicho receptor es multiplicada en el mismo por un multiplicador de frecuencia utilizándose la energía de corriente alterna de la frecuencia multiplicada para accionar un relé de salida enviando impulsos desde dicho receptor a la línea de salida.
