Abstract
LA INVENCION SE REFIERE A UN METODO PARA AFINAR LA FRECUENCIA RESONANTE DE UN FILTRO EN UN COMBINADOR, QUE SE SUMINISTRA PARA COMBINAR LAS SEÑALES DE VARIOS CANALES DE RADIO, A LA FRECUENCIA PORTADORA DE UNA SEÑAL DE ENTRADA A DICHO FILTRO. LA POTENCIA (TA) DE LA SEÑAL DE SALIDA DEL FILTRO MENCIONADO (14A) SE MIDE EN UNA BANDA DE FRECUENCIA ESTRECHA ALREDEDOR DE LA FRECUENCIA PORTADORA DE LA SEÑAL DE ENTRADA MENCIONADA. ADEMAS, LA POTENCIA (RA) DE LA SEÑAL REFLEJADA POR EL FILTRO MENCIONADO (14A) SE MIDE EN UNA BANDA DE FRECUENCIA ESTRECHA ALREDEDOR DE LA FRECUENCIA PORTADORA DE LA SEÑAL DE ENTRADA MENCIONADA. POSTERIORMENTE SE FORMA UNA MEDIDA DE LA PROPORCION ENTRE LAS DOS MEDICIONES DE POTENCIA. LA FRECUENCIA RESONANTE DEL FILTRO MENCIONADO (14A) SE AJUSTA DE MANERA QUE MAXIMISE ESTA MEDICION .
