    An amplifier is an electronic device that increases the voltage, current or power of a signal. Used in wireless communication, broadcasting and in audio equipment, they can be categorized as either weak-signal amplifiers or power amplifiers. Weak-signal amplifiers are used primarily in wireless receivers, acoustic pickups, audio tape players and compact disc players. Power amplifiers are used in wireless transmitters, broadcast transmitters and for sound reinforcement.
