Abstract :
Uses the Pareto optimal multi-criterion optimization method to design low sensitivity state-space digital filters for the parallel form and cascade form structures. The designs balance the desire to match a desired filter response with the desire to produce a low sensitivity filter. Some work on direct form II designs which solidifies some previous work is shown. The authors find that pole/zero cancellation pairs added to a desired direct form II filter are Pareto optimal
