Abstract

PROCEDIMIENTO Y DISPOSITIVO PARA CODIFICAR INFORMACION DIGITAL. CONSISTE EN PRODUCIR UNAS TRANSICIONES EN UNOS PUNTOS DE REFERENCIA DE LAS CELDAS DE LOS BITIOS QUE CONSTITUYEN LA INFORMACION DIGITAL, CUANDO ESTOS PASAN DE UN "CERO" LOGICO O UN "UNO" LOGICO, CUANDO SE DETECTAN DOS O TRES "UNOS" SEGUIDOS, CUANDO SE DETECTAN, POR LO MENOS, DOS "UNOS" SEGUIDOS DE UN "CERO" O CUANDO SE DETECTAN TRES O CUATRO "CEROS" SEGUIDOS. EL PROCESO SE REALIZA POR MEDIO DE UNOS REGISTROS DE DESPLAZAMIENTO (2,6 Y 8), DE UNA MEMORIA ROM, DE UN CIRCUITO LOGICO (11) Y DE UNA SERIE DE SEÑALES DE RELOJ (CO1, CP2, LD).
