Planar linear discrete delayed systems w(k +1) = Aw(k)+Bw(k −m), k = 0,1,... are considered, where A and B are constant matrices and m is a positive integer denoting a delay. Recently, formulas have been derived for the general solution of such systems provided that one eigenvalue of A is nonzero while the other being zero, and that matrices A and B satisfy the conditions known for so-called weakly delayed systems. Conditions characterizing weakly delayed systems imply that there are only two roots of the relevant quasi-characteristic equation. The present paper is concerned with the problem of a possible replacement of the delayed systems in question with non-delayed planar ones x(k +1) = Cx(k), k = 0,1,... having an identical general solution. It is shown that this is possible if a transient interval is passed and possible forms of the matrix C are found. Some relationships with previously known results are commented.
