Abstract

PERFECCIONAMIENTOS INTRODUCIDOS EN UN FILTRO DE DATOS MUESTREADOS PARA PROPORCIONAR MUESTRAS DE SEN/ALES FILTRADAS.COMPRENDE UN REGISTRO DE DESPLAZAMIENTO CON UN TERMINAL DE ENTRADA ACOPLADO PARA RECIBIR LAS SEN/ALES DE ENTRADA, CON ETAPAS DE RETARDO DISPUESTAS EN CASCADA Y EN SERIE Y TERMINALES DE SALIDA DISPUESTAS EN PARALELO. TAMBIEN COMPRENDE UNA PLURALIDAD DE SISTEMAS MULTIPLICADORES DE SEN/ALES PARA PONDERAR SEN/ALES APLICADAS A ELLOS Y SISTEMAS PARA SANEAR LAS SEN/ALES PONDERADAS PROCEDENTES DE LA PLURALIDAD DE SISTEMAS MULTIPLICADORES. LAS SUMAS DE SEN/ALES PONDERADAS CORRESPONDEN A UNA SEN/AL DE SALIDA PROCEDENTE DEL FILTRO, CARACTERIZADOS POR R GRUPOS DE ELEMENTOS DE ALMACENAMIENTO. CADA GRUPO ES CAPAZ DE RESPONDER A RESPECTIVAS SEN/ALES DE RELOJ PARA ACOPLAR SIMULTANEAMENTE SEN/ALES PROCEDENTES DE LOS TERMINALES DE SALIDA DE REGISTRO A ELEMENTOS RESPECTIVOS DE DICHA PLURALIDAD DE ELEMENTOS DE ALMACENAMIENTO EN UN GRUPO PARTICULAR. LA SEN/AL DE ENTRADA DE FILTRO ES UNA SEN/AL DE VIDEO COMPUESTA MUESTREADA A CUATRO VECES LA FRECUENCIA DE LA SUBPORTADORA DE CALOR.
