#4 An amplifier is a device.. usually electronic, that magnifies information to a more powerful signal at
the amplifier's output. Amplifiers are usually based on electronic principles but may utilize hydraulics or magnetics.

signal must be increased. Audio amplifiers can
increase the microwatts developed by a microphone to more than a million watts of power required to fill a stadium during a concert. Satellites use amplifiers to strengthen television & telephone signals so they can be received easily when beamed back to Earth.
