Abstract

SE PRESENTA UN APARATO DE FILTRO PARA EL FILTRO DE PEINADO DE SEÑALES DE VIDEO PAL O NTSC QUE INCLUYE CIRCUITERIA DE COMPROBACION (14, 16, 18) PARA COMPROBAR LA SEÑAL DE VIDEO EN LOS 45 (GRADOS) CON RELACION A LOS EJES I.Q O U.V.. LA SEÑAL COMPROBADA SE ACOPLA A UN CIRCUITO DE RETARDO (24, 26) DISPUESTO PARA SUMINISTRAR CONCURRENTEMENTE MUESTRAS DE VIDEO DE TRES LINEAS HORIZONTALES SUCESIVAS, DESIGNADAS SUPERIOR MEDIA E INFERIOR. LAS MUESTRAS DE VIDEO DE LA LINEA MEDIA SE COMBINAN (28, 32) CON LAS MUESTRAS SELECCIONADAS ALTERNATIVAMENTE DE LAS LINEAS SUPERIOR E INFERIOR PARA SUMINITRAR UNA SEÑAL CENTRADA.
