PROCEDE ET DISPOSITIF DE CONVERSION NUMERIQUE D'UN SIGNAL D'ENTREE DERIVE D'UN SIGNAL ELECTRIQUE DELIVRE PAR UNE CHAINE D'ACQUISITION D'UN CAPTEUR

摘要

The method comprises a step (E30) of decomposing the input signal over a complete decomposition base comprising K+1 decomposition elements resulting in the determination of components associated with each element of the base, a step (E40) of formulating an output signal on the basis of all or some of these components, and a step (E50) of providing the output signal to a processing device, in which the K+l elements wk, k - 0,..., K, of the decomposition base have fundamental frequencies f(wk) defined by: f(w0) =αand f(wk) =αx p(k), where : a is a determined real constant, and p(k), k - 1,..., K, are K consecutive prime numbers with p(1).
