Abstract
EMISORA DE RADIODIFUSION EN FRECUENCIAS ULTRACORTAS. UNA SUBPORTADORA DE 57 KHZ, SE PRODUCE EN UN GENERADOR (5), Y ES MODULADA EN AMPLITUD (6) JUNTO CON OTRAS INFORMACIONES. EN UN NIVEL DE ADICION (7) SE UNIFICA ESTA ONDA MODULADA CON LA RESTANTE MODULACION UTIL DEL EMISOR, Y LA SEÑAL RESULTANTE SE ENVIA AL MODULADOR DE FRECUENCIA (2) DEL EMISOR. EL MODULADOR DE AMPLITUD (6) DISPONE DE DOS ENTRADAS DE MODULACION, UNA (BK) PARA UNA IDENTIFICACION COORDINADA CON LA ZONA DE EMISION, Y OTRA (DK), PARA UNA INFORMACION DE CONTENIDO REAL. DE APLICACION ESPECIALMENTE EN EMISORAS PARA INFORMACION SOBRE EL ESTADO DEL TRAFICO RODADO.
