Abstract
Perfeccionamientos en circuitos de control de descodificadores para televisión en color del tipo que comprenden un componente de luminancia, componentes de sincronización de deflexión a los ritmos respectivos de línea y de imagen, y componentes de luminancia y de impulsión que presentan una relación de temporización mutua predeterminada y que alternan en ase sobre una base de línea por línea, un canal de crominancia para elaborar la señal de color, una pluralidad de demoduladores de color para demodular fases elegidas del componente de crominancia, medios para proporcionar control de conmutación de línea por línea de uno de los demoduladores, y donde el funcionamiento apropiado del receptor exige que el demodulador conmute en sincronismo de temporización correcto con la alternación línea por línea de las señales recibidas por el receptor, teniendo lugar una fuente de impulsos de excitación periódicos al ritmo de línea; medios de temporización acoplados a los medios de conmutación que responden a los impulsos de excitación para proporcionar señales de temporización de frecuencia de media línea para determinar la conmutación línea por línea.
