Abstract
Various realizations asserting to produce the alias-free discrete-time Wigner distribution have been reviewed and analyzed by Costa and Boudreaux-Bartels (see ibid., vol.47, no.5, p.1463-74, May 1999). Here, a simple alias-free form of the pseudo-Wigner distribution is proposed. It is obtained from the fact that the sampled signal can formally be considered as a multicomponent signal.
