Okay, so I understand that R
E is used to stabilize the transresistance instability in the transistor to combat distortion by lowering the amplification gain for the DC signal. C
E is used to bypass R
E for the AC signal and thereby obtaining the full gain of the amplification, but only for the AC signal. What I don't understand is why this construction doesn't distort the AC signal because its unaffected by the negative feedback caused by R
E? I would expect the AC signal to also be sensitive to the small h
FE fluctuation caused by temperatur and current changes?
