???????

2. The Bode diagram of the forward-path transfer function of a unity-feedback control system is obtained experimentally when the forward gain is fixed to certain value \( \mathrm{K} \). a) Find the gain and phase margin of the system from the diagram the best you can read. Is the system stable or unstable? b) Repeat part (a) if the gain is ten times higher. Show your results on the Bode diagram.
