Why do we use emitter resistors?

The aim of an AC signal amplifier circuit is to stabilize the DC biased input voltage to the amplifier and thus only amplify the required AC signal. This stabilization is achieved by the use of an Emitter Resistance which provides the required amount of automatic biasing needed for a common emitter amplifier.
