Abstract

Método para controlar un codificador-descodificador de modulación por impulsos codificados (¿codec¿ de PCM) que convierte señales analógicas entrantes en vocablos de modulación por impulsos codificados (vocablos de PCM) transmitidos en una primera frecuencia de reloj, y que, en una segunda frecuencia de reloj, convierte los vocablos de PCM entrantes en unas muestras de señal analógica salientes.
