Résumé : A novel approach to the spectral analysis of periodic digital filters is proposed based on a symmetry property which is described by the action of a group on the signal space. Under this action, the signal space decomposes into reducing spaces which define the frequency response of periodic signal filters as the restriction of the filter operator to the reducing spaces.
