Waves

Electromagnetic Waves - Transmission.

Analogue Signals and Digital Signals.

Information today is being increasingly transmitted using digital signals.
Digital signals have advantages over analogue signals.
The advantages are increased capacity and better quality.

Increased capacity means that
more information can be sent by digital signals
than analogue signals in the same time,
using the same optical fibre or carrier wave.
