Abstract

VISUALIZACION DE UNA IMAGEN GENERADA A PARTIR DE UNA SEÑAL AUXILIAR COMO INSERTO EN LA IMAGEN GENERADA A PARTIR DE UNA SEÑAL PRINCIPAL. CONSTA DE UNA FUENTE PRINCIPAL DE SEÑAL DE VIDEO Y UNA FUENTE AUXILIAR DE SEÑAL DE DATOS MUESTREADAS CON UNA FRECUENCIA PREDETERMINADA DE MUESTREO, ESTANDO CONSTITUIDA CADA UNA DE ELLAS POR INTERVALOS SUCESIVOS DE LINEA HORIZONTAL Y SE CARACTERIZA PORQUE EL APARATO CONSTA DE UN SISTEMA DE SUBMUESTREO HORIZONTAL ACOPLADO A LA FUENTE DE SEÑAL. CONSTA ADEMAS DE ELEMENTOS DE SUBMUESTREO VERTICAL ACOPLADOS A LOS DE SUBMUESTREO HORIZONTAL. ESTOS INCLUYEN UNA MEMORIA INTERMEDIA CON UN NUMERO SUFICIENTE DE BITIOS PARA RETENER LAS MUESTRAS PROPORCIONADAS.
