Abstract

L'invention concerne la prospection sismique. Le filtre de l'invention comprend essentiellement : des circuits de sommation 13-18 qui font la somme, par paires, des signaux qui proviennent de sismomètres 1-12; des éléments de retard doubles 19-24; des soustracteurs 25-30 qui combinent les signaux de sortie de chaque élément de retard; et un amplificateur de sommation final 37 qui fournit le signal filtré destiné à être enregistré. Application à la prospection pétrolière.
