Abstract

EN UN CODIFICADOR DE CINTA PARCIAL CON VARIOS GRADOS DE FILTRADO, EL PROBLEMA CONSISTE EN ELIMINAR LAS INTERFERENCIAS QUE SURGEN EN OTRAS CINTAS PARCIALES, EN LAS QUE ORIGINARIAMENTE NO SE PRESENTARIAN, MEDIANTE LA REDUCCION DE LOS DATOS O RUIDO DE CUANTIFICACION EN UNA CINTA PARCIAL. TALES INTERFERENCIAS SURGEN CUANDO SE REFLEJAN LAS PARTES CON INTERFERENCIAS. SEGUN EL INVENTO, LOS GRADOS DE FILTRADO SE MIDEN DE TAL MANERA QUE SUS ZONAS DE TRANSCION NO SE SOLAPAN EN NINGUN LUGAR DE LA BANDA DE FRECUENCIAS. PREFERENTEMENTE, LAS FRECUENCIAS DE CIERRE SON IGUALES A LOS GRADOS PARTICULARES DE FILTRADO. LOS FILTROS PUEDEN EMPLEARSE EN CODIFICADORES PARCIALES, PREFERENTEMENTE PARA LA REDUCCION DE DATOS EN LA TRANSMISION DE RADIO DIGITAL.
