Suppose that the tests w1w2w3w4 = 0100, 1010, 0011, 1111, and 0110 are chosen randomly to test the circuit in this image. What percentage of single faults is detected using these tests?
This image consists of two 2-input AND gates, one 3-input OR gate, and one inverter. Inputs w1 and w2 are connected to the first AND gate and the output of this AND gate, labeled as c, is connected to one of the inputs of the OR gate. Input w2 is connected to the inverter and the output of the inverter, labeled as b, is connected to one of the inputs of the second AND gate. The output of this second AND gate, labeled as d, and input w4 are connected to the remaining 2 inputs of the 3-input OR gate. The output of the 3-input OR gate is labeled as f.
