Abstract

APARATO PARA LA REALIZACION SIMULTANEA DE LA CONVERSION DE UNA INFORMACION NUMERICA EN UNA SEÑAL NUMERICA DE CODIGO NRZI. CONSTA DE UN CIRCUITO LOGICO AL QUE SE APLICA UNA SEÑAL NUMERICA DE BASE Y UNA SEÑAL NUMERICA CONVERTIDA, TENIENDO DICHO CIRCUITO LOGICO UN TERMINAL DE CONTROL Y UN PRIMER DISPOSITIVO LOGICO QUE SE SELECCIONA CUANDO SE APLICA A DICHO TERMINAL DE CONTROL UN PRIMER VALOR DE SEÑAL; DE UN DISPOSITIVO PARA DETECTAR SI EL VALOR DE CADA UNO DE LOS BITIOS DE NUMERO PAR DE LA INFORMACION NUMERICA ES UN CERO DIGITAL; DE UN SEGUNDO DISPOSITIVO PARA DETECTAR SI DOS BITIOS DE NUMERO PAR DETECTADOS QUE TIENEN UN VALOR NUMERICO CERO Y UN BITIO DE NUMERO IMPAR, TIENEN UN COMPONENTE CORRIENTE CONTINUA; Y DE UN DISPOSITIVO PARA CONVERTIR LA INFORMACION DE UNA SEÑAL NUMERICA DE CODIGO NRZI, UTILIZANDO LA SEÑAL DE DETECCION.
