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?
