Consider the same closed-loop system as in the previous exercise: With 0.5(z-0.5) (z+1) (z+0.4)(z-1)² K Q(z) = P(z) H (2) = H(z) = In the previous exercise you determined the value of the gain K that will give poles on the unit circle. A discrete-time system with complex-conjugated poles on the unit circle, at z = eiwih will have undamped oscillations given by the argument of the complex poles. If the sampling period is 0.2 seconds, what is the frequency of these undamped oscillations?
