Abstract

ESTE SISTEMA DETECTOR DE MATERIALES MAGNETICOS, AL QUE SE REFIERE ESTA INVENCION, CONSISTE EN UN CONJUNTO FORMADO POR UN CIRCUITO ELECTRONICO, EN EL QUE EXISTE UN MICROPROCESADOR QUE EMITE LA SEÑAL A PARTIR DE LAS QUE SE GENERAN EL RESTO DE SEÑALES QUE SE PRECISAN, PASANDO POR UN SINTETIZADOR DE FRECUENCIAS DE LAS QUE SALEN LAS SEÑALES A UNAS BOBINAS QUE FORMAN LA ANTENA EMISORA, UNA VEZ FILTRADAS Y AMPLIFICADAS. ESTAS SEÑALES ORIGINAN LA DE LA MUESTRA, QUE SE RECOGE EN OTRA ANTENA RECEPTORA DE LA QUE, AMPLIFICADA Y FILTRADA CONVENIENTEMENTE, Y ELIMINADOS TODOS LOS POSIBLES ELEMENTOS DE DISTORSION, SON ENVIADAS A UNOS FILTROS DE FRECUENCIA ADECUADA PARA OBTENER A LA SALIDA UNAS SEÑALES DE AMPLITUD PROPORCIONAL A LAS GENERADAS EN LA MUESTRA, QUE LLEVADAS AL MICROPROCESADOR, SON ANALIZADAS Y PROPORCIONAN LOS DATOS DE SALIDA QUE SE RECOGEN EN UN INDICADOR.
