Homework Statement


Hi,

I'm given a transfer function, and am suppose to draw Bode plot from it.

H(s) = ( 2000s (s - 1) ) / (s + 2000)^2

I'm wondering what to do for the zero at s = 1? Should I just solve this normally, as every example we have done and every example I've seen uses simple zeros/poles (with "+" in the middle, and positive number.

So any idea? :)

p.s. I'm not looking for solution, I'm just little puzzled by the minus

It'll have the same amplitude spectrum as a zero in the left-half plane, so just go about it like you normally would. There's a significant difference in its phase spectrum, however, if you need to include it.
