Abstract

SISTEMA ELECTRONICO PARA MODULAR LA VELOCIDAD DEL HAZ CROMATICO DE VIDEO EN LA REPRODUCCION DE IMAGENES POR TELEVISION QUE MEJORA LA NITIDEZ DE LA IMAGEN. LA FUENTE DE VIDEO EN COLOR (11) ALIMENTA POR MEDIO DE FILTRO (14), PROCESADOR (16) Y MATRIZ (19) A UN CINESCOPIO (21). SE CONECTAN UNAS BOBINAS DE DEFLEXION (23,25) HORIZONTAL Y VERTICAL PARA DESARROLLAR UNA TRAMA DE SEÑALES QUE EXPLORE LA PANTALLA DEL CINESCOPIO DE COLOR (21). LA VELOCIDAD DE ESTAS SEÑALES DE EXPLORACION SE CONTROLA POR MEDIO DE UN LIMITADOR, QUE COMPRENDE UN AMPLIFICADOR (50) EN ETAPA EMISOR COMUN Y DOS AMPLIFICADORES DIFERENCIALES (61,71).
