Consider the feedback system in Figure 10.43, where
A phase lag compensator is designed for the system to give additional attenuation at higher frequencies. The compensator is
When compared with the uncompensated system (that is, Gc(s) = 1), the compensated system utilizing the lag compensator:
a. Increases the phase lag near the cross-over frequency.
b. Decreases the phase margin.
c. Provides additional attenuation at higher frequencies.
d. All of the above.
