- Reduction in cost of hardware.
- High speed.
- High Reliability.
- Design is easy.
- Result can be reproduced easily.
What is the difference between analog and digital signals?
Viewed from afar, the wave function below may seem smooth and analog, but when you look closely there are tiny discrete steps as the signal tries to approximate values: That's the big difference between analog and digital waves. Analog waves are smooth and continuous, digital waves are stepping, square, and discrete.
