The invention relates to a method for processing a signal, in which method a sample set is formed and a set of absolute values is formed. The method includes A) arranging the elements of the absolute value set in the ascending order; B) setting a threshold value; C) determining the number of elements of a reference set to be formed; D) forming a reference set; E) computing a reference value by multiplying the mean or median of the reference set by the threshold value; F) comparing the greatest element of the reference set with the reference value; G) increasing the number of reference set elements; H) reiterating the preceding steps D to G until the predetermined ending condition is fulfilled; I) forming an accepted absolute value set and a sample set by deleting the greatest element from the reference set.
