Abstract :
A state-space representation of an elementary 2-dimensional digital network is presented. The problem of determining the frequency response starting from its state-space equation is reduced to solving two sets of linear simultaneous equations in real unknowns at each pair of frequencies. The efficiency and the computational aspects of the proposed method are also discussed.
