I do really have a good question but I have to draw a circuit diagram and paste here. But I am not getting the process.

Q) Is it better to have output impedance more or input impedance?

Q)can I please have the complete full-fleged meaning of "Emitter-Follower"
It really troubles me to understand.;)

you get the most power transfer when the output impedance matches the input impedance of the following stage.A low impedance circuit is strong, a high impedance circuit is weak. a high impedance circuit has more voltage and less current, a low impedance circuit has more current and less voltage.
