hey,
how does exactly negative feedback changes impedance???
i understand that the ouput signal is reversed in phase and fed back into an earlier stage of the amp ... in the case of a transistor is that the emitter???....
but that then causes a drop in voltage??? ... or current???
then after that how exactly this will influence the input impedance???
