Band faults: Efficient approximations to fault bands for the simulation before fault diagnosis of linear circuits
Anil Pahwa, R.A. Rohrer · IEEE Transactions on Circuits and Systems · 1982
"Band faults," the approximate movements of nominal worstcase boundaries with catastropic faults, are much more efficiently computed than the "fault bands" that they approximate. Derived from a simulation before test, band faults can be used to create a fault dictionary that is supposed to isolate single element catastrophic faults. By no means general, the approach when applied to several example linear circuits nonetheless has yielded promising results.
