发明名称 APPAREIL ET PROCEDE DE COMPENSATION DE DERIVE D'UNE HORLOGE LOCALE UTILISEE COMME FREQUENCE D'ECHANTILLONNAGE
摘要 The invention relates to an apparatus and a method for data acquisition, the apparatus being characterized in that it comprises an analog/digital converter (510) sampling at an imperfect frequency FE provided by a local clock (100) data acquired by a sensor (500) thus providing a series of sampled and dated data E[k], a time-stamping module (300) for measuring the frequency error of the local clock (100) by determining the sampling dates according to a universal time UTC(t), and a resampling module (400) for correcting the sampled and dated data E[k].
