Question

At which frequency does the magnitude of the system becomes zero db?

Answer 1

At "C) Grain crossover frequency" the magnitude of the system becomes zero db

What are gain and phase margins?

Gain and phase margins are two safety indicators that tell you about the system's stability.

What is gain crossover frequency?

• The gain crossover frequency is the one at which the phase margin is adjusted in such a way that if we change the threshold further, the system becomes unstable.
• It is when the magnitude of the system is zero dB.
