Abstract

UN RECEPTOR DE FM QUE CONTIENE UNA SECCION DE RF, UNA PRIMERA ETAPA MEZCLADORA SINTONIZABLE PARA UNA CONVERSION DE FRECUENCIA DE UNA SEÑAL DE RECEPCION DE FM DE RF EN UNA PRIMERA SEÑAL DE FRECUENCIA INTERMEDIA, UN DISPOSITIVO DE FI Y UN DEMODULADOR DE FM. PARA OBTENER EL MAYOR GRADO DE INTEGRACION POSIBLE, AL TIEMPO QUE SE MANTIENE UN PROCESAMIENTO DE LA SEÑAL SIN DISTORSIONES, EL RECEPTOR DE FM DE LA INVENCION TIENE INCORPORADOS UNOS ELEMENTOS EN LA TRAYECTORIA DE LA SEÑAL PARA CONVERTIR UNA SEÑAL DE UNA SOLA FASE EN UN PAR DE SEÑALES EN UNA CUADRATURA DE FASE MUTUA, APLICANDOSE DICHO PAR DE SEÑALES EN CUADRATURA DE FASE A UNAS TRAYECTORIAS DE SEÑAL EN FASE Y EN CUADRATURA DEL DISPOSITIVO DE FI, TENIENDO INCORPORADO DICHO DISPOSITIVO DE FI UN FILTRO DE FI POLIFASICO EN DICHAS TRAYECTORIAS DE LA SEÑAL EN FASE Y EN CUADRATURA Y UNA CARACTERISTICA DE PASABANDA SIMETRICA ALREDEDOR DE SU FRECUENCIA DE RESONANCIA, ESTANDO DICHO FILTRO DE FI POLIFASICO ACOPLADO AL DEMODULADOR DE FM.
