Abstract

METODO Y CIRCUITOS PARA LA CORRECCION DE LA DEFLEXION DIGITAL EN TUBOS DE RAYOS CATODICOS DE USO EN TELEVISION. CARACTERIZADO PORQUE LAS SEÑALES EN FORMA DE DIENTE DE SIERRA UTILIZADOS PARA LA DEFLEXION HORIZONTAL Y VERTICAL SE MANTIENEN SIN SER CORREGIDAS Y PORQUE LA RELACION DE TIEMPO DE LAS SEÑALES DE VIDEO DIGITALES QUE CONTROLAN LOS CONVERTIDORES DIGITALES ANALOGICOS UTILIZADAS PARA DICHAS SEÑALES CAMBIA CON RESPECTO A LA RELACION DE TIEMPODE LAS SEÑALES DE VIDEO DIGITALIZADAS POR ELVALOR DE LA CORRECCION QUE DEPENDE DEL LUGAR RESPECTIVO DE UNA IMAGEN SPOT EN LA PANTALLA DEL TUBO. DIVERSOS DISPOSITIVOS ANALIZAN Y DIGITALIZAN LAS SEÑALES UTILIZADAS. LOS VALORES DE CORRECCION A UTILIZAR SE ALMACENAN EN MEMORIAS DE SOLO LECTURA.
