OpenStudy (anonymous):
what do you mean input graph? Emitter follower circuit simply has a gain almost 1 or unity, whatever you input, same output you will get... the main purpose of this circuit is to avoid loading effects due to its high input impedance and low output impedance...
OpenStudy (kenljw):
The input impedance is hie plus (hfe + 1) RE, this is how the emitter resistor is reflected to the base is all cases except in this case RE is larger than in a collector output voltage gain circuit.
