| Abstract(in English) | This paper proposes a new method of the Gramian-preserving frequency transformation for linear discrete-time systems. In the proposed method, we realize frequency transformation by replacing each delay element of a discrete-time system with an allpass function that has the normalized lattice structure. The Gramian-preserving frequency transformation based on this approach yields the transformed systems in closed form in terms of realizations of a prototype system and an allpass function of the normalized lattice structure. From this fact, it is shown that the proposed method can realize the Gramian-preserving frequency transformation without using the complicated algebraic computations that are required in the conventional method. |
