Abstract
Perfeccionamientos en circuitos de identificación de señal de color, aplicables a sistemas para utilizar señales de televisión en color del tipo SECAM en el cual un circuito binario, para producir una señal de salida de onda prácticamente cuadradas que aparecen a la mitad del ritmo de exploración de línea de imagen, se incluye para sincronizar la demodulación de por lo menos una primera y una segunda portadoras de señal de color de diferentes frecuencias que aparecen cíclicamente de una forma alternativa en una secuencia de línea por línea y se modulan durante intervalos de exploración de línea con señales de información de imagen de color respectivas, cuya señal de tipo SECAM comprende además un primer y un segundo componentes, respectivamente, a las de dichas portadoras y que aparecen durante intervalos de retroceso de línea adyacentes en el tiempo a una portadora de color asociada.
