Q.6
The transfer function of a compensator is given as Gc(s) is a lead compensator if
A. a =1, b = 2
B. a = 3, b = 2
C. a = –3, b = –1
D. a = 3, b = 1
Explaination / Solution: both option (A) and (C) satisfier but option (C) will pot polar and zero as RHS of s-plane thus not possible option (A) is right
