Hello everyone,

Finals are coming up and I am trying to study for my Introduction to Analog Electronics class. It is my first electronics class and we have covered simple things such as passive components, passive filters, power amps, op amps, and active filters.

I cannot figure out this problem for the life of me.

I was wondering if i could show you guys what I have been able to figure out for this and maybe you can tell me what I am missing to help me understand these better?

I am currently just stuck trying to find the Q point for Transisitor 3. I know tat the DC load line has an X intercept of Vcc because that is always the x intercept of DC load lines, and the Y intercept is Vcc/(Re+Rc) but seeing as how there is no collector resistor I think its just Vcc/R7, right?

Now i have to figure out the quiescent current and quiescent voltage from from Vc to Ve. I know that Vc is Vcc for this transistor because its collector is hooked directly to Vcc, and i know that Ve is simply Vout, this means that Vce for the DC load lines Q point is Vcc-Vout. But I have no clue how to find Vout.

for part b of this problem I am pretty sure all i need to do is use the DC load lines Q point to calculate the AC load line, and then find the most voltage that results in a Vce that is still on the AC load line? I am not sure what "mid frequency" means exactly...

for part C of this problem I do not know how to determine the corner frequency of this circuit, it seems way to complicated to analyze (but maybe i am over thinking it).

Any help is greatly appreciated!
