Hi, I'm working on the emitter follower amplifier and I've got confused at some place. Till now had no problems in determining other type of amplifiers' output impedances but the emitter follower is different I gues. The circuit schematic is attached. I've understood where the input impedance came from but why the output impedance is only r(e) and why not r(e)+[Rsig/(B+1)].
Appriciate any concern
