Show how emitter amplifier work as a buffer amplifier, Electrical Engineering

Assignment Help:

Q. Due to what special property does an emitter amplifier work as a buffer amplifier?

 The circuit design of the emitter follower is such that it has a high input impedance and a low output impedance. Due to this it is capable of giving power to a load connected to its output without requiring much power at the input. It thus works as a buffer amplifier.
