Abstract

PARA EVITAR LA COPIA DE UNA MEMORIA (28) SE HA PREVISTO UN GENERADOR DE NUMEROS ALEATORIOS (50) QUE PROPORCIONA UN NUMERO A CADA APARATO EN EL QUE ESTA DISPUESTO. ESTE NUMERO SE GUARDA A CONTINUACION EN DICHA MEMORIA (28) PARA UNA POSTERIOR VERIFICACION. EL GENERADOR ESTA CONSTITUIDO POR UN DIVISOR POTENCIOMETRICO FORMADO POR DOS RESISTENCIAS (R1 Y R2) CUYOS VALORES ESTAN DETERMINADOS CON UNA GRAN TOLERANCIA. APLICACION EN LAS REDES CELULARES AMPS, ETC...
