amplifiers
Signal strength increasers
Amplifiers are devices that increase the strength or magnitude of a signal.
In electronics, an amplifier boosts electrical signals—audio amplifiers power speakers, guitar amplifiers shape and project sound: He cranked the amplifier to eleven.
The term extends to anything that intensifies or magnifies: Social media serves as an amplifier for outrage.
In scientific contexts, amplifiers increase the amplitude of waves or the gain of signals.
