A general method is proposed for the design of optimal 1D IIR digital filters via linear programming. the method is based upon the formulation of an appropriate linear problem which assures satisfactory approximation error for the filter's magnitude frequency response. the linear problem does not require differential correction methods or other iterative techniques for its solution, thus resulting in a computationally efficient algorithm. Analytical examples are presented to illustrate the efficiency of the method for the design of stable 1D recursive digital filters.
