- Digital signal maintain there quality over long distances.
- Digital signal carry more information per second than analog signals.
- Digital signal system are generally easy to design.
- Reprogramming is possible.
- Size and Cost is less .
- Power dissipation is less.
- Memories are stable.
- Information Storage is easy.
Disadvantage : Real world is mainly analog, human does not understand digital data.
