The loop transfer function of an LTI system is G(s)H(s) =K(s+1)(s+5)/s(s+2)(s+3). For K>0, the point on the real axis that does not belong to the root locus of the system is
A. -0.5
B. -2.5
C. -3.5
D. -5.5
Answer:C
The loop transfer function of an LTI system is G(s)H(s) =K(s+1)(s+5)/s(s+2)(s+3). For K>0, the point on the real axis that does not belong to the root locus of the system is
A. -0.5 B. -2.5 C. -3.5 D. -5.5
Explanation: The points present on the root locus are right to the odd number of poles and zeroes.
