Abstract

1.1.- PROCEDIMIENTO Y DISPOSITIVO PARA MEJORA DE DISOCIACION DE SEÑALES DIGITALES. 2.2.- EN SEÑALES DIGITALES DE TELEVISION TRANSFORMADAS EN UNA ZONA DE FRECUENCIA SE PRODUCEN EN REDUCIDOS NUMEROS DE LUGARES EN EL CALCULA DE LOS COEFICIENTES EN BASE DE FALTAS DE CURVATURA INEXACTITUDES EN LA ESTRUCTURA DE LAS SEÑALES DE IMAGEN RETRANSMITIDAS. EL INVENTO CREA EL REMEDIO DE AUMENTAR LOS COEFICIENTE DE LOS VALORES DE SEÑAL TRANSFORMADAS CONSIGUIENTES A UN PRIMER COEFICIENTE, POR EJEMPLO, UN COMPONENTE SIMILAR Y TRAS LA TRANSFORMACION POSTERIOR SE VUELVEN A REDUCIR. EL INVENTO ES UTIL EN SISTEMAS DIGITALES CON ELABORACION EN BLOQUE, EN LOS QUE SE PRODUCE A CAUSA DEL NUMERO DE BIT LIMITADO EN EL CALCULA UNA CURVATURA DE LOS COEFICIENTES ESPECTRALES TRANSFERIDOS.
