Electronics A-Z

Amplifier   An electronic circuit that increases the strength of an electric signal. For example, an amplifier can convert the weak signal from a radio tuner into a signal strong enough to power a speaker.

Analogue   Whereas digital systems use only two values, 1 or 0, to store data, analogue, or non-digital systems, use an infinite range of values. In an analogue circuit, current can be of any strength, while in a digital circuit, current can only be on or off.
