Hello, i am trying to get the thevenin equivalent between B an ground but i cant not find it. Thank you for the help

Not really. The whole idea of a Thevenin equivalent requires that we be talking about a linear circuit. But the large signal behavior of most transistor circuits is very nonlinear. So what we normally do is treat the circuit as two circuits superimposed -- a DC circuit and an AC circuit with the excursions of the AC circuit being small enough that we can pretend it is linear, at least over the range of the excursions and at least to a degree that is acceptable for our purposes.Is there a method that gives you both in one? Can i use thevenin when the circuit mixes both dc and ac sources?
