zeros are the roots of Y(S) and poles are the roots of X(S).

question: if you have a zero in your transfer function then at your bode plot

(20log (abs(T(S))), the function starts ro rise?

and the same with a pole: when you have one your function starts to go down instead of raisin' to infinity??

Yes, I know. The complex numbers...bla bla

Anyone can truly explain what's going on?

Thanks
