Automatic Control Systems - Engineering

Q1:

The functions and have

A identical magnitude and phase curves

B identical magnitude curves but different phase curves

C different magnitude curves but identical phase curves

D different magnitude and phase curves

ANS:B - identical magnitude curves but different phase curves

Magnitude are the same. i.e. . However phase angles are different because the phase angle of 1 - jωT3 is negative but that of 1 - jωT3 is positive.
