Abstract

The problem of minimizing l2 -sensitivity subject to l2 -scaling constraints for two-dimensional (2-D) separable-denominator state-space digital filters is investigated. The coefficient sensitivity of the filter is analized by using a pure l2 -norm. An iterative algorithm for minimizing an l2 -sensitivity measure subject to l2 -scaling constraints is then explored by introducing a Lagrange function and utilizing an efficient bisection method. A numerical example is also presented to illustrate the utility of the proposed technique.
