Abstract
PARA EL REGISTRO INTRINSECAMENTE SEGURO DE SEÑALES BINARIAS DE UN TRANSMISOR (13) CON RESISTENCIA INTERNA VARIABLE, EL TRANSMISOR ESTA CONECTADO POR MEDIO DE UNA RESISTENCIA (11) DE MEDICION DE CORRIENTE A LA SALIDA (10) DE TENSION DE UNA FUENTE (2-9) DE TENSION DE CORRIENTE CONTINUA. COLOCADO EN LA SALIDA (10) DE TENSION SE DISPONE DE UN DIVISOR DE TENSION (14) DE ETAPAS MULTIPLES, CUYAS TOMAS DE TENSION (15) ESTAN CONECTADAS A COMPARADORES (16,17,18) DE TENSION QUE ESTAN CONECTADOS RESPECTIVAMENTE A UNA CONEXION (19,20,21) DE ENTRADA, MIENTRAS QUE LAS OTRAS CONEXIONES (22,23,24) DE ENTRADA DE LOS COMPARADORES (16,17,18) DE TENSION ESTAN CONECTADAS A LA CONEXION (26) DE LA RESISTENCIA (11) DE MEDICION DE CORRIENTE COLOCADA SOBRE EL TRANSMISOR (13). LOS ACOPLADORES OPTICOS ESTAN COLOCADOS DESPUES DE LOS COMPARADORES (16,17,18) DE TENSION PARA LA TRANSMISION DE RESULTADOS COMPARATIVOS A UN DISPOSITIVO (30) DE EVALUACION.
