it is tempting compare a repeater to an amplifier,but the comparison is inaccurate .According to Forouzan,an amplifier cannot discriminate between the intended signal and noise. it amplifies equally everything fed into it. a repeater does not amplifying the single '.It regenerates the single, it creates a copy, bit for bit, at the original strength.
a repeater is a regenerator .'not an amplifier.
