I have a seemingly simple problem. Perhaps the solution is obvious and I just don't see it, or perhaps I am missing something and I just have not realized it. This is not for any class or assignment, but for a small project that I am working on. I need help figuring out the general equations to solve for the resistor values in a voltage-divider-biased BJT, as shown:
**broken link removed**
Vcc, Ib, and Beta are all known, but all of the resistor values are unknown. I have been looking at guides all over the internet and have seen a number of equations listed, but I cannot find a single source that clearly lists all of the equations that I need to solve for all of the unknowns. Any time that I have seen the equations done out in an example, it was always with the resistor values already known and working backwards to find everything else from there. I have been trying to work out all of the equations on my own from what I have seen, but all I have managed to do is give myself a headache. (I looked at the Wikipedia article on transistor biasing, but, even there, I was unable to make sense of the equations listed.)
I would really appreciate it if someone could point me in the direction of a website that might give me a clearer explanation, or just list out the equations right here. If I am somehow missing some crucial piece of information to solve this, I would also appreciate advice on that as well. If it turns out that I am just an incorrigible idiot, I apologize for wasting your time.
