Abstract

SEGUN EL CODIGO AMI, UN NIVEL LOGICO O ESTA REPRESENTADO POR UN VALOR NULO DE LA SEÑAL CODIFICADA, Y UN NIVEL LOGICO (1) ESTA REPRESENTADO ALTERNATIVAMENTE POR DOS VALORES ALGEBRAICOS OPUESTOS. UN EJEMPLO PREFERENCIAL DE REALIZACION DE DECODIFICADOR AMI SEGUN LA INVENCION COMPRENDE: RESISTENCIAS (23, 24) PARA PROPORCIONAR DOS SEÑALES QUE TIENEN RESPECTIVAMENTE UN VALOR IGUAL Y UN VALOR OPUESTO AL DE LA SEÑAL CODIFICADA; ESTAS SEÑALES EN FUNCION DE LA POLARIDAD DE LA SEÑAL CODIFICADA, PREVISTA PARA LA PROXIMA VEZ EN QUE REPRESENTARA EL ESTADO LOGICO (1); TENSION DE UMBRAL POSITIVO, SEA CUAL SEA LA POLARIDAD PREVISTA PARA LA SEÑAL CODIFICADA; ARAR LA SEÑAL SELECCIONADA CON EL VALOR DE UMBRAL, Y PROPORCIONAR UNA SEÑAL BINARIA DE VALOR 1 SI EL VALOR DE LA SEÑAL SELECCIONADA ES MAYOR QUE LA TENSION DE UMBRAL POSITIVA, O DE VALOR O EN EL CASO CONTRARIO; AL RITMO DE LOS BITS DE NIVEL LOGICO 1 DECODIFICADOS POR EL DECODIFICADOR DE MANERA A PREDECIR LA POLARIDAD (P'') DE LA SEÑAL CODIFICADA, PARA LAPROXIMA VEZ REPRESENTARA EL ESTADO LOGICO 1. APLICACION EN LA TRANSMISION DE DATOS, SEGUN EL CODIGO AMI O PR4.
