Abstract

L'invention a pour objet un dispositif pour produire un signal d'épreuve ayant une distorsion de valeur déterminée. On engendre des impulsions de données, des impulsions de distorsion et un signal composite pour chaque impulsion de donnée. Chaque signal composite comprend une partie principale d'impulsion ainsi qu'au moins une des impulsions de distorsion. Application aux essais d'appareillages d'émission et de réception de données numériques.
