Popis: This paper deals with the subject of minimizing roundoff noise under the restrictions of $l_{2}$ -norm dynamic-range scaling for state space digital filters in which the subject is solved by simultaneously optimizing realization and error feedback. That is to say, a useful technique for minimizing roundoff noise is explored by relaxing the scaling restrictions into only one restriction on the trace of a square matrix and solving the relaxed subject with an efficient matrix iterative equation as well as two recursive scalar equations. The utility of the present technique is demonstrated through a numerical example.
