So the previous problems I was working had an open format

It was called a two power supply emitter controlled circuit  :loco

So the next set of problems it is closed and is called universal circuit biasing  xP

So why all the excitement  xP well at least it (to me) resembles something actually encountered in real life like in the wild  :tu:

And it starts to somewhat resemble the diagrams of common emitter, common collector and common base.

Speaking of which I need to have a major epiphany because every time I look at the three diagrams I see the same damn thing so I start looking at what is connected to what and....it all comes out the same.  :grr

But that is coming up and I saw that there are capacitaters involved so all in due time.. :'(

And I know one is the most common  xP  and inverts a signal. 🚦

Ok maybe it's that not big of a deal. it seems R1 and R2 are "bleeder resistors"  xP
