2-D discrete time lossless bounded real functions: minimal state space realisation
A circuit realisation for two-dimensional (2-D) nth order discretetime lossless bounded real functions, with minimum number of delay elements, is presented. Based on this circuit realisation the corresponding matrix vectors A, b, c' of the Givone-Roesser 2-D state space model, are derived. The dimension of the 2-D state space model is minimal.
