  • Abstract
    It is argued that the derivation of the formulas to compute the output noise and the 2-D noise matrix given by W.-S. Lu and A. Antoniou (ibid., vol.CAS-33, p.965-73, Oct. 1986) is incorrect. Moreover, the formula for the 2-D noise matrix obtained does not have the dual form to the formula for the 2-D covariance matrix
