【Abstract】 Using perturbation theories and a distance in manifolds, this paper initiates a testability condition for k-faults diagnosis in analog circuits with tolerance. In this condition, this paper mathematically elaborates how testability of a circuit with tolerance depends on both nominal data and measurable signals of the circuit. In addition, it is shown that this condition provides a theoretical basis for reasonably application of extreme methods to locate faults.更多还原
