Abstract

EL SISTEMA CORRIGE SEÑALES DE VIDEO RETARDANDO (95,96,98) LA SEÑAL DE SALIDA DE LA MEMORIA (50) EN FUNCION DE DISTORSIONES DE RELOJ DE LEER Y ESCRIBIR, MIDIENDOSE LA DISTORSION DE ESCRIBIR PARA CADA CICLO DE LEER-ESCRIBIR DE LA MEMORIA. LA DISTORSION DE LEER (ENGANCHE 66) DEL PRIMER CICLO DE LEER CORRESPONDE A LA DISTORSION DE ESCRIBIR (ENGANCHE 64) AL COMIENZO DE ESE CICLO. LA DISTORSION DE LEER DEL SEGUNDO CICLO DE LEER SE OBTIENE AÑADIENDO A LA DISTORSION DE LEER UN SEMIPERIODO DE LINEA DE LA SEÑAL DE ENTRADA DE VIDEO Y TOMANDO SU PARTE FRACCIONARIA.SE DETECTA (68) LA PARTE ENTERA DE LA SUMA INICIANDO EL COMIENZO DEL SEGUNDO CICLO DE LEER. LA DIFERENCIA (86) ENTRE LA SEÑAL DE DISTORSION DE LEER (64) Y EL DOBLE (84) DE LA SEÑAL DE DISTORSION DE ESCRIBIR (66) DETERMINA EL RETARDO DE LA SEÑAL DE VIDEO.
