Abstract

Cette invention se rapporte à des systèmes et à des procédés qui fournissent des filtres non médians et non linéaires (56) pour des signaux dérivés d'évènements biologiques. Ces systèmes et ces procédés sélectionnent un ensemble de n valeurs échantillons agencées par rapport au temps à partir de l'entrée des signaux biologiques dérivés. Ces systèmes et ces procédés agencent les n valeurs échantillons dudit ensemble dans des positions ordonnées selon une permutation prédéterminée. Ces systèmes et ces procédés sélectionnent l'une des positions ordonnées z à l'intérieur de la permutation, z étant égal à un nombre entier positif impair, supérieur ou égal à un mais inférieur ou égal à n. Ces systèmes et ces procédés génèrent une sortie traitée (54) comprenant la valeur échantillon qui occupe la position ordonnée z dans la permutation.
