example on frequency response analysis: bode plot<br />
It is to remind that K = 2.39 is the critical gain or the gain which<br />
cause the system to be marginally stable.<br />
In a manner similar to that employed in continuous-time<br />
systems, the frequency of oscillation at K = 2.39 can be found<br />
from the w 2 row of the array. We may obtain the auxillary<br />
equation as such,<br />
(1 − 0.0381)w 2 + 0.924K| K=2.39 = 0.9089w 2 + 2.181 = 0<br />
