Abstract:

The purpose of this contract was to formulate computational techniques for automatically isolating faults in electronic circuitry to the component level and to implement the technique utilizing a digital computer. The technique can be applied to linear circuits and to circuits containing small nonlinearities. The technique formulated uses circuit equations and represents an advance in the state-of-the-art from the conventional, sequential, gono-go, automatic checkout techniques. All circuit equations used in the diagnosis are generated numerically by the computer from the specification of the circuit schematic in coded form and from the nominal values of all circuit components. Three 3 diagnostic techniques are included. They involve the numerical network admittances which are automatically generated from the coded schematic. The required number of test terminals is minimal. Author
