Abstract
RED DE FILTRO DE PASO DE BANDA DE FRECUENCIAS POR EFECTO DE LA INDUCCION DE CORRIENTES INVERSAS EN SEGMENTOS DE LINEAS IMPRESAS, CARACTERIZADA PORQUE SE EXCITAN DOS CIRCUITOS RESONANTES CON INDUCTANCIAS EN LINEA IMPRESA, DISPUESTAS FISICAMENTE DE FORMA QUE CREAN CAMPOS YUXTAPUESTOS EN PUNTOS EQUIDISTANTES, DISPONIENDOSE DE SEGMENTO DE LINEA IMPRESA EN LOS QUE SE INDUCEN CORRIENTES INVERSAS POR EFECTO DE LOS CAMPOS, OBTENIENDOSE A LA SALIDA SEÑALES EN UN ANCHO DE BANDA DETERMINADO POR LAS FRECUENCIAS DE RESONANCIA DE LOS CIRCUITOS RESONANTES. PRESENTA CARACTERISTICAS DE ALTA SELECTIVIDAD, BAJA ATENUACION DE PASO Y BAJO RETARDO DE GRUPO. PEQUEÑO TAMAÑO Y GRAN INDEPENDENCIA DE SUS ELEMENTOS DE AJUSTE. REALIZADO EN HIBRIDO ENCAPSULADO, PERMITE USARLO COMO COMPONENTE EN SISTEMAS SELECTIVOS, SIN NECESIDAD DE AJUSTE. CAMPO DE APLICACION MAS IMPORTANTE TV Y RADIOTELEFONIA. UNA IMPORTANTE APLICACION ES LA POSIBILIDAD DE REALIZAR CON EL UN SISTEMA DE FILTRO PROGRAMABLE DIGITAL.
