Abstract

L'invention concerne le domaine de l'échographie médicale. Le circuit de commande de gain 100 d'un dispositif d'échographie comprend en particulier un circuit intégrateur 101 qui est associé à un interrupteur 112 commandé par un multivibrateur monostable 114. Grâce à cette configuration, le signal de sortie du circuit intégrateur ne commence à croître ou à décroître qu'au bout d'une durée de retard définie par le multivibrateur monostable 114. On peut ainsi faire varier le gain avec une vitesse déterminée, au bout d'une durée de retard choisie. Applications aux appareils d'échographie.
