Abstract A method is described for the design of octagonally symmetric, non‐symmetric half plane, two‐dimensional IIR digital filters with integer coefficients. The design problem is formulated as an integer non‐linear problem and the solution is achieved via an integer non‐linear optimization algorithm. An example illustrates the features of the proposed approach.
