Abstract

RECEPTOR PROVISTO DE UN CIRCUITO SINTONIZADOR EXPLORADOR QUE REALIZA LA EXPLORACION DE ACUERDO CON LOS DATOS DE SINTONIZACION ALMACENADOS EN UN CIRCUITO DE MEMORIA, PUEDIENDO DICHO CIRCUITO SINTONIZADOR EXPLORADOR INICIAR UNA ACCION DE EXPLORACION BAJO LA INFLUENCIA DE UNA SEÑAL DE INICIACION, GENERADA CUANDO SE HACE DEMASIADO DEBIL LA INTENSIDAD DE CAMPO RECIBIDA DEL TRANSMISOR. CARACTERIZADO PORQUE EL RECEPTOR ESTA PROVISTO DE UN CIRCUITO DE RETARDO (61) DE LA SEÑAL DE INICIACION DE LA EXPLORACION, QUE DEPENDE DEL COMPORTAMIENTO DE LA INTENSIDAD DE CAMPO RECIBIDA DEL TRANSMISOR, SIENDO CONTROLADO DICHO CIRCUITO DE RETARDO POR UN CIRCUITO DE CONTROL (47) QUE AJUSTA EL RETARDO DE TIEMPO A UN VALOR.
