Abstract

Circuit d'acquisition numérique de signal à constante d'intégration variable.Ce circuit comprend : - des premiers moyens (10) apte à calculer la moyenne d'un nombre variable N d'échantillons successifs du signal;- des seconds moyens (201 ) aptes à indiquer aux premiers moyens (10) ledit nombre variable N, ce nombre N dépendant du signal à acquérir (2),- une mémoire (30) mémorisant le résultat (R) du calcul de moyenne.Digital signal acquisition circuit with variable integration constant. This circuit comprises: - first means (10) able to calculate the average of a variable number N of successive samples of the signal; - second means (201) able to indicate to the first means (10) said variable number N, this number N depending on the signal to be acquired (2), - a memory (30) storing the result (R) of the averaging calculation.
