Poles an Zeros



Hello,

Could someone explain to me Poles and Zeros.
What does a Pole do and what does a zero do and how they interact
together.
How does phase, gain, and delays relate to them?

If a book or a link could be recommended along with a what math needs
to be used. (maybe a course outline to work from)

I am right now working on systems which I have an good idea on how
they work but I don't seem to have the underlying understanding or how
to calculate.

Some fully worked out examples I can look at would also be helpful. I
just seem to be missing parts. I have found information. But I am
having some issues putting it all together. A number of fields all
converge and I am not able to find a path and seem to be jumping
around and not getting anywhere.
The area I am interested in are digitally controlled power converters
(DC/AC and DC/DC power supplies).

Thank you,
Rob
