In the voltage amplification stage of a three stage audio amp there is often a coupling capacitor connected to base and collector/ input and output. I think this is as a high pass filter so as to provide local negative feedback

I think I thought of it IS it just for feedback, acting as a really high freq filter? Sometimes you just have to ask to know

What's about this? Where a capacitor is between base and collector (NPN). I have formulated some of my own theories (it seems like this is totally unknown of on the internet, and the books I've looked at don't explain it), but I have thought of flaws to all my theories. Can anyone please...
