We investigate their ability to remove different noise types, namely symmetrical and skewed, as well as heavy- and light-tailed, thereby uncovering the true underlying signal. These smoothers prove very effective in removing noise originating from the same distribution as that noise which originally contaminated the signal.enSouth African Statistical AssociationLULU operatorsNonlinear smoothers for signalsNoise removalArticle
