How does an amplifier work? - Explain that Stuff
https://www.explainthatstuff.com/amplifiers.html
An audio amplifier might work better with some sound frequencies than others; the range of frequencies over which it works satisfactorily is called its bandwidth. Ideally, it has to produce a reasonably flat response or linear response with a wide range of different input signals (so the gain is pretty much constant across a range of frequencies).
