Abstract
Perfeccionamientos en los convertidores de segmento digital/análogo, para la conversión de una palabra PCM de varias plazas, aplicada en forma paralela a entradas digitales, en una tensión de salida análoga de acuerdo con la ley A de COITT, componiéndose la palabra PCM de ocho Bits, de los que el Bit VZ indica el signo, los Bits S1, S2, S3 forman un número binario, que determina el segmento de la ley A y los Bits B1, B2, B3, B4, forman un número binario, que determina el lugar dentro del mencionado segmento, componiéndose dicho convertidor de un convertidor lineal digital/análogo, que contiene el mecanismo de red de pesada y suministra una corriente-tensión, conectado detrás de éste.
