For the transfer function G(s) H(s) = 1 / s(s+1) (s+0.5), the phase cross-over frequency is
A. 0.5 rad/sec
B. 0.707 rad/sec
C. 1.732 rad/sec
D. 2 rad/sec
Answer:B
For the transfer function G(s) H(s) = 1 / s(s+1) (s+0.5), the phase cross-over frequency is
A. 0.5 rad/sec B. 0.707 rad/sec C. 1.732 rad/sec D. 2 rad/sec
Explanation: Phase cross over frequency is calculated at the point where magnitude of the polar plot is 1.
