   Amplifiers, AC

An electronic amplifier is a device for increasing the power of a signal. It does this by taking power from a power supply and controlling the output to match the input signal shape but with a larger amplitude. An idealized amplifier can be said to be "a piece of wire with gain", as the output is an exact replica of the input, but larger.
