It is of significantly importance in relation to the problem of diagnosis of deviation faults in linear analog circuits to check whether or not it is possible to uniquely determine the element-values in a given linear analog circuit from the node-voltage measurements at its accessible nodes and then of giving a method for actual computation of the element-values if it is possible, under the assumption that i) the circuit is of known topology (and of known element-kinds if possible) and ii) the actual value of each element-value of the circuit almost always deviates from the design value and is not known exactly. In this paper, the problem of checking the unique determinability of the element-values is called the element-value determinability problem, and its solutions which have been obtained until now are reviewed in perspectives to designing a publicly available user-oriented analog circuit diagnosis system.
