Abstract
Un dispositivo de circuito convertidor para convertir señales de color bivalentes en una señal monocroma que puede ser obtenida en una salida del mismo con una amplitud que es diferente para cada combinación de colores, cuyo circuito convertidor tiene tres entradas a cada una de la cuales puede ser suministrada una señal de color bivalente, y comprende también un circuito sumador, caracterizado porque el circuito convertidor comprende además un circuito no lineal para obtener una pluralidad de amplitudes aumentadas de la señal monocroma para combinaciones de señales de color correspondientes a la más baja amplitud, distinta de cero, de la señal monocroma.
