摘要

A digitising assembly of the oversampling type comprises an analog-digital converter (2) producing, at a frequency F=kf, samples of reduced format p and a digital filter (3) which, by adding a certain number n of oversamples, produces validated samples of format P at the frequency f, at instants fixed by a clock. In order to synchronise the sampling instants with respect to an external event which can occur at any time, a temporary storage memory (5) is interposed between the converter (2) and the filter (3) and, as a function of the instant of arrival of this event, the appropriate samples to be sent to the filter in order to be added are selected. …??Application to the synchronisation of seismic data acquisition systems for example. …IMAGE…
