Abstract

LA INVENCION SE REFIERE A UNA DISPOSICION DE CIRCUITO PARA RECONOCIMIENTO Y SUPRESION DE CANAL VECINO EN UN RECEPTOR DE RADIODIFUSION, EN PARTICULAR RECEPTOR FM, CON EL CUAL CUANDO APARECEN SEÑALES DE CANAL VECINO PERTURBADORAS SE REDUCE LA AMPLITUD DE BANDA EN EL CAMINO DE SEÑAL ZF. PARA EL RECONOCIMIENTO DE LA MAGNITUD DE LA PERTURBACION SE DETECTAN EN LA ENTRADA Y EN LA SALIDA DE UN FILTRO ZF EL NIVEL ZF DE LA ANCHURA DE BANDA DISMINUIDA Y SE COMPARA UNA CON OTRA. POR MEDIO DE LAS SEÑALES DERIVADAS CORRESPONDIENTES SE CONECTAN LAS AMPLITUDES DE BANDA DIFERENTES EN LA VIA DE SEÑAL ZF AL FILTRO ADAPTADO A LA MAGNITUD DE LA PERTURBACION.
