Fault diagnosis in analog circuits using element modulation
Aaron Walker, W.E. Alexander, Parag K. Lala · IEEE Design & Test of Computers · 1992
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.>
