- B.Converting a digital signal back into an analogue form.
- C.Filtering out noise from an analogue signal.
- D.Increasing the frequency of an analogue signal.
Model answer
What a good answer should say
- Measuring the amplitude of an analogue signal at regular intervals.
Explanation
Why this works
Sampling involves taking measurements of the amplitude of an analogue signal at regular intervals to convert it into a digital signal, which can then be processed and stored.
