Abstract

The realization, circuit and state space of two-dimensional (2D) nth order separable all-pass digital filters is considered. The matrices A, b, c′ and the scalar d of the Givone-Roesser state space model are presented in closed form. The dimension of the state space model is minimal. In addition, the corresponding circuit implementation of the filter is given.
