Which pole is dominant?

Dominant pole is a pole which is more near to origin than other poles in the system. The poles near to the jw axis are called the dominant poles.

What is the use of dominant pole?

The dominant pole approximation is a method for approximating a (more complicated) high order system with a (simpler) system of lower order if the location of the real part of some of the system poles are sufficiently close to the origin compared to the other poles.

Which one is dominant pole out of the two?

Dominant pole concept: The pole which is closer to the imaginary axis is called as the dominant pole as this pole contributes more in the response of the system.

What is the dominant pole in frequency response?

The lowest frequency pole is called the dominant pole because it dominates the effect of all of the higher frequency poles.
