1.	If the performance index of a phase lead compensator is (s+a)/ (s+b) and that of a lag compensator is (s+p)/(s+q), then which one of the following sets of conditions must be satisfied?(a) a>b and pb and p
Answer» Correct option is (d) aq For explanation I would say: In PHASE LEAD compensator, zero is nearer to origin. In phase LAG compensator, POLE is nearer to origin.
