Assume that the Nyquist diagram of a given open-loop system G(s) looks like the following figure where the
dashed line is the asymptote. If we calculate the intersection of this asymptote with the Real axis "A" and
the corresponding frequency at the intersection of the plot with the Imaginary axis "wi", then which one is
true?
100(s – 1)
s(s + 2)2
G(s) =
(a) A=50, wi <3
(b) A= 25, wi <4
(c) A=50, 3 < wq < 4
(d) A= 25, wi > 3
