Hi,

I have got a few simple questions:

1. Is a dominant pole the one with the least natural frequency?

2. Is the pole with least natural frequency necessarily with the maximum damping aswell?

3. Although the I have asked above two questions, another things that is confusing me is that isn't damping ratio for a whole transfer function i.e zeta? Why do we say that there is a particular damping ratio for every pole?


Sorry for noob questions. Kindly clarify as soon as possible.


Cheers,
Raazi
