Hello,
I've been trying to educate myself about amplifiers (using op amps), with the final goal to build an audio amplfier of my own.
I stumbled upon this design and tried to analyse it.
From my understanding this is a negative feedback circuit. C1 acts as a high pass filter. R1 controls the gain. I can't figure out what C2's purpose is.
I would like some help there and would also like to know if any of my observations are wrong.
Thanks in advanced
