Au lieu d'utiliser la valeur de l'échantillon en tant que donnée à transmettre, on peut prendre la différence entre cette valeur et la valeur prévue d'une certaine manière à partir de données antérieures connues. Cette différence une fois quantifiée, on a ce que l'on appelle la modulation par impulsions et codage différentielle (MICD).
