Abstract: In this paper we study stability problems associated with the previously developed design for test (DFT) methodology applied to ladder filters. A solution based on simple modification of the basic DFT strategy is proposed which allows on-line testing of ladder filters. A filter example demonstrates the feasibility of the solution.
