Abstract

UN RECEPTOR DE LLAMADAS SELECTIVO QUE INCLUYE UN DECODIFICADOR QUE TIENE UN OSCILADOR DE RELOJ DE REFERENCIA Y UNA CPU QUE TIENE UN OSCILADOR DE RELOJ OPERATIVO DE LA CPU. EL DECODIFICADOR INCLUYE UN CIRCUITO DE TEMPORIZACION PARA GENERAR UNA SEÑAL DE TEMPORIZACION SINCRONIZADA CON UNA SEÑAL DE SINCRONIZACION QUE CONTIENE UNA SEÑAL POCSAG Y UN CIRCUITO DE CORRECCION DE ERRORES BCH PARA EXTRAER EL CODIGO DE MENSAJE DE UNA SEÑAL POCSAG. SI LA CPU RECIBE UN CODIGO DE MENSAJE DEL DECODIFICADOR, CUANDO NO SE INTRODUCE UNA SEÑAL DE TEMPORIZACION DESDE EL DECODIFICADOR, LA CPU ALMACENA EL CODIGO DE MENSAJE EN LA RAM DE LA CPU O EN UNA ZONA DE MEMORIA INTERMEDIA DE LA RAM EXTERNA CONECTADA A LA CPU. EN ESTE CASO, LA CPU FUNCIONA CON UNA PRIMERA SEÑAL DE RELOJ GENERADA POR EL OSCILADOR DE RELOJ DE REFERENCIA. CUANDO EL DECODIFICADOR ENVIA UNA SEÑAL DE TEMPORIZACION A LA CPU, LA CPU LEE EL CODIGO DE MENSAJE EN LA RAM O EN LA ZONA DE MEMORIA INTERMEDIA Y PROCESA EL CODIGO DE MENSAJE CON UNA SEGUNDA SEÑAL DE RELOJ GENERADA POR EL OSCILADOR DE RELOJ OPERATIVO DE LA CPU Y LA SEGUNDA SEÑAL DE RELOJ TIENE UNA FRECUENCIA MAYOR QUE LA FRECUENCIA DE LA PRIMERA SEÑAL DE RELOJ.
