Abstract

EL INVENTO REIVINDICA UN METODO (Y UN SISTEMA) PARA CORREGIR UNA SEÑAL ANALOGICA EN CUANTO A COMPONENTES DE SEÑAL INDESEADAS, QUE COMPRENDE LAS OPERACIONES DE (Y MEDIOS PARA) RECIBIR LA SEÑAL ANALOGICA; DIGITALIZAR LA SEÑAL ANALOGICA PARA GENERAR UNA SEÑAL DIGITAL EN BRUTO; TRATAR LA SEÑAL DIGITAL EN BRUTO PARA GENERAR UNA SEÑAL DIGITAL DE CORRECCION; CONVERTIR LA SEÑAL DE CORRECCION DIGITAL EN UNA SEÑAL DE CORRECCION ANALOGICA; Y APLICAR LA SEÑAL DE CORRECCION ANALOGICA A LA SEÑAL ANALOGICA PARA GENERAR UNA SEÑAL ANALOGICA CORREGIDA. EL METODO Y EL SISTEMA PUEDEN ADAPTARSE PARA CORREGIR UN GRUPO DE COMPONENTES INDESEADAS, O PARA CORREGIR UN TREN DE SEÑALES ANALOGICAS. EL METODO Y EL SISTEMA PUEDEN UTILIZARSE PARA CORREGIR SEÑALES DIGITALES. EN UNA REALIZACION PARTICULAR, EL METODO Y EL SISTEMA PUEDEN EMPLEARSE PARA CORREGIR LAS FALTAS DE UNIFORMIDAD DE DESFASE Y/O DE GANANCIA DE LAS SEÑALES DE SALIDAPROCEDENTES DE ELEMENTOS DETECTORES EN UNA AGRUPACION DE PLANO FOCAL.
