Abstract :
Analog fault diagnostic methods are reviewed. A branch fault-diagnosis technique that requires a single excitation source at one test frequency is introduced. The technique lets users construct linearly independent branch-diagnosis equations by modulating selected network elements. An example of the technique applied to a two-stage amplifier is given.<>
