Question:
If the phase angle at gain cross-over frequency of a system is -116°, then the phase margin will be
If the phase angle at gain cross-over frequency of a system is -116°, then the phase margin will be
Show Hint
Phase margin is always measured from −180°, so use PM = 180° + (Phase at gain crossover).

- −116°
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Phase margin (PM) = 180° + Phase at gain crossover frequency
PM = 180° − 116° = 64°
