What is the main difference between analogue and digital signals?.
- A.Analogue signals are continuous, while digital signals are discrete.
- B.Analogue signals use binary code, while digital signals use waveforms.
- C.Analogue signals can only represent two states, while digital signals can represent multiple states.
- D.Analogue signals are less susceptible to noise than digital signals.
Model answer
What a good answer should say
- Analogue signals are continuous, while digital signals are discrete.
Explanation
Why this works
Analogue signals vary continuously over time, representing information in a continuous form, while digital signals represent information in discrete steps or levels, typically using binary code.
