Abstract

LA INVENCION SE REFIERE A UN PROCESO PARA LA DETECCION DE UN ELEMENTO CONDUCTOR ELECTRICO EN UN DOCUMENTO, EN EL QUE SE ACOPLA UNA SEÑAL CON FRECUENCIA PORTADORA MODULADA CON, AL MENOS, UN ELECTRODO TRANSMISOR. ESTA SEÑAL SE TRANSMITE, POR LO MENOS, A UN ELECTRODO DE RECEPCION A TRAVES DEL ELEMENTO CONDUCTOR ELECTRICO, PROCESANDOSE LA SEÑAL MODULADA RECIBIDA PARA EL RECONOCIMIENTO DEL ELEMENTO CONDUCTOR ELECTRICO. EL ELEMENTO CONDUCTOR ELECTRICO FORMA DE ESTA MANERA UN ELEMENTO ACOPLADOR CAPACITIVO ENTRE EL ELECTRODO DE TRANSMISION Y DE RECEPCION.
