yes, to have complex conjugate in the RHP, Q>.5 correct me if am wrong....
@buddypoor,
is it possible to satisfy BH criterion when Q<1/2?
I am afraid, we speak about different functions.
* Aaaron is right - the poles of the
closed-loop transfer function are in the RHP (conjugate-complex).
* Raja was (and is) referring to the
open-loop characteristics.
The WIEN network has two LHP poles and an open-loop pole-Q<0.5. Nevertheless, after closing the loop it will oscillate. Why not - if the Barkhausen condition is fulfilled?
