Abstract

RECEPTOR DE FRECUENCIAS ULTRACORTAS. EL DECODIFICADOR RADIOFONICO DEL RECEPTOR SE COMPLETA CON UN FILTRO (22), EN PARALELO CON OTROS FILTROS, EN LA SALIDA DEL DEMODULADOR (12). DESPUES DE ESTE FILTRO SE HA CONECTADO UNA INSTALACION DE MEDICION, QUE INDICA EL GRADO DE MODULACION DE AMPLITUDES DE LA SUBPORTADORA. CUANDO ESTE GRADO SE ELEVA DEL 60% AL 90%, LA INSTALACION DE MEDICION GENERA UNA SEÑAL DE CONTROL. DE APLICACION ESPECIALMENTE EN RECEPCION DE INFORMACION SOBRE EL ESTADO DEL TRAFICO RODADO.
