A closed loop system, employing lag-lead compensator \(\mathrm{G}_{c}(\mathrm{~s})\) is shown in the Fig. M8.14:
If \(\mathrm{G}(\mathrm{s})\) has 3 poles in the left half of s-plane, then the slope of the Bode plot for \(\left|\mathrm{G}(\mathrm{s}) \mathrm{G}_{c}(s)ight|\) in the highest frequency range will be

(a) - \(20 \mathrm{~dB} /\) decade
(b) - \(40 \mathrm{~dB} /\) decade
(c) - \(60 \mathrm{~dB} /\) decade
(d) \(-80 \mathrm{~dB} /\) decade.
