摘要：

A new expression of evaluating l(2)-sensitivity for generalized direct-form II structure of two-dimensional (2-D) separable-denominator digital filters is derived and analyzed. Unlike the previous work, l(2)-sensitivity is analyzed for the filter structure instead of its state-space realization. Then the resulting l(2)-sensitivity measure is compared with that deduced in a recent study of generalized direct-form II state-space realization of 2-D separable in denominator digital filters. In a numerical example, the new l(2)-sensitivity measure is minimized with respect to free parameters subject to l(2)-scaling constraints by an exhaustive search over a set of discrete values of finite cardinality, and the results are compared with those obtained by existing techniques.
