(a) The Table 1 gives a fault list for the circuit <strong>of</strong> Figure 3, after equivalence fault<br />
collapsing. Fill in the blanks with equivalent fault <strong>set</strong>s for each listed fault.<br />
(Validity check: the total number <strong>of</strong> faults in table should be 38)<br />
(b) Assume that you are applying exhaustive test <strong>set</strong> for the circuit in Figure 2. In<br />
the Table 2, mark all the faults that are detected by each vector. Note that only<br />
