Analogue signal

An analogue signal is effectively a wave, in the form you’ve probably seen before. They take on continuous values - that just means that an analogue signal at a point may represent the value 0.7, 0.421, or any other value between 0 and 1!

Analogue signals store continuous values.

Computers don’t work with analogue signals, so they need to be converted into a digital signal if we want to use them in a computer.
