a lag compensator that provides an attenuation of $$20dB$$ and a phase lag of $${45^0}$$ at the frequency of $$3\sqrt 3 $$ rad/s
B
a lead compensator that provides an amplification of $$20dB$$ and a phase lead of $${45^0}$$ at the frequency of $$3$$ rad/s
C
a lag - lead compensator that provides an amplification of $$20dB$$ and a phase alg of $${45^0}$$ at the frequency of $$\sqrt 3 $$ rad/s
D
