Abstract

TRADUCTOR PARA MODULACION POR IMPULSOS CODIFICADOS (MIC). SE TRATA DE UN TRADUCTOR PARA LA CONVERSION DE UNA PALABRA DE ENTRADA EN MIC COMPANDIDO QUE INCLUYE UN CODIGO DE SEGMENTO DE 3 BITS Y UN CODIGO DE SALTO DE 4 BITS EN UNA PALABRA DE SALIDA MIC LINEAL. INCLUYE UN DECODIFICADOR CON UN LOGICO ACOPLADO, UN ELEMENTO PUEDE MODIFICAR EL CODIGO DE SALTO, UN MULTIPLICADOR, UN SUMADOR Y UN CODIFICADOR. LOS ELEMENTOS MODIFICADORES INCLUYEN UN REGISTRO DE DESPLAZAMIENTO DE SEIS ETAPAS PARA ALMACENAR LAS VARIABLES Y EL CODIGO DE SALTO. ESTE TRADUCTOR PUEDE REALIZAR SELECTIVAMENTE LA CONVERSION SEGUN LA LEY-A O LA LEY-MU. EL DISPOSITIVO ESTA ADAPTADO PARA DETERMINAR LA FUNCION JF(LBAD2 4B2 (C1)D2 KKBC, DONDE J ES LA PALABRA DE SALIDA, L ES EL CODIGO DE SALTO Y A, B, C SON VARIABLES.
