damping factor - xi or zeta?
damping factor - xi or zeta?
(OP)
I know it's a stupid question but I'd like to know so I can be consistent with the rest of the world.
In all of my textbooks the 2nd order system is described as
H(s) = w0^2 / (s^2 + 2*squiggle*w0*s + w0^2).
What is the correct greek letter for that squiggle. (I looked up the symbols and eta and xi both look pretty similar to me).
Thanks.
