How does noise affect analogue signals compared to digital signals?.
- A.Noise has no effect on analogue signals but significantly affects digital signals.
- B.Noise can distort analogue signals, while digital signals can often correct for noise.
- C.Noise affects both signals equally.
- D.Noise only affects digital signals.
Model answer
What a good answer should say
- Noise can distort analogue signals, while digital signals can often correct for noise.
Explanation
Why this works
Analogue signals are more susceptible to distortion from noise, which can affect the quality of the signal. Digital signals, on the other hand, can often include error correction mechanisms to mitigate the effects of noise.
