Abstract
EN UN RECEPTOR DE RADIODIFUSION SE CONECTA O DESCONECTA UNA COMPRESION DINAMICA DE LA SEÑAL, EN DEPENDENCIA DE QUE SE HUBIERA REALIZADO UNA COMPRESION DEL MISMO TIPO EN EL LADO EMISOR. COMO INDICATIVO DE ESTA COMPRESION EN EL LADO EMISOR SE TRANSMITE UN BIT DE IDENTIFICACION. ES OBJETIVO DE LA INVENCION, CONSEGUIR UN RECEPTOR DE RADIODIFUSION, QUE ACCIONA UNA CONEXION O DESCONEXION AUTOMATICA DE UNA COMPRESION DE AMPLITUD, PERO SIN QUE SALGA UN BIT DE IDENTIFICACION TRANSMITIDO. LA SEÑAL DE AUDIO RECIBIDA SE APLICA EN UN CIRCUITO (4) ANALIZADOR DE SEÑAL, QUE AVERIGUA LOS VALORES DE ESCALA DE LA SEÑAL Y GENERA UNA TENSION (US) DE CONEXION DEPENDIENTE DE LOS FACTORES DE ESCALA. SE APLICA ESPECIALMENTE PARA RECEPTORES DE RADIODIFUSION EN UN VEHICULO O CON REGISTRO DE SEÑAL A CONTINUACION.
