Abstract
TRANSMISORES EN SUBESTACIONES DE LAS SEÑALES QUE TRANSMITE EL SISTEMA EN EMISORAS Y EN RANURAS DE TIEMPO DEDICADAS A UNA ESTACION PRINCIPAL. LA ULTIMA ESTACION CONVIERTE LAS SEÑALES RECIBIDAS A SEÑALES DIGITALES POR MEDIO DE UNA CIRCUITERIA DE PROCESO INCLUIDO EN SU RECEPTOR. ESTA CIRCUITERIA DE PROCESAMIENTO REALIZA LOS PASOS DE UN PROCESO ITERATIVO Y EN CADA PASO DERIVA DESDE UN LIN DE SEÑAL RECIBIDA A UN VALOR UMBRAL RELACIONADO CON UNA CARACTERISTICA DE LA SEÑAL. ESTE VALOR ES ALMACENADO A TRAVES DE UN CONVERTIDOR ANALOGICO A DIGITAL AD EN UNA MEMORIA MEM. LA CARACTERISTICA DEL LIN DE SEÑAL ES ENTONCES COMPARADA EN UN COMPARADOR QUE CONSISTE EN DOS CIRCUITOS COMPARADORES C1 Y C2 Y UN CONMUTADOR S, CON UN VALOR UMBRAL PREVIAMENTE ALMACENADO PARA LA SUBESTACION LA CUAL ENVIA EL LIN. ESTE VALOR ES ANTERIOR A LA RECEPCION DEL LIN, ESTO ES, DURANTE UNA RANURA DE TIEMPO PREVIA, APLICADO P.EJ. C1 A TRAVES DE UN CONVERTIDOR ANALOGICO A DIGITAL DA2. EL RESULTADO DE LA COMPARACION ES A TRAVES DES GENERADA EN DOUT Y REPRESENTA LA CONVERSION DIGITAL DEL LIN. LA POTENCIA DE LAS SEÑALES TRANSMITIDAS SE CONTROLA POR UN CIRCUITO INCLUIDO EN LOS TRANSMISORES DEL SISTEMA. ESTE CIRCUITO COMPARA LOS VALORES DE POTENCIA DE PICO DE UNA SEÑAL DE MANTENIMIENTO RETRO ACOPLADA A TRAVES DE UN DIODO DE SENTIDO INVERSO D CON VALORES DE REFERENCIA REF1 Y REF2 Y CONTROLA UN CIRCUITO LASER L BASADO EN EL RESULTADO DE LA COMPARACION ALMACENADO EN UNA MEMORIA MEM2.
