Explain the concept of quantisation in the context of digital signals.
Model answer
What a good answer should say
- Quantisation is the process of mapping the sampled values of an analogue signal to a finite set of levels, effectively rounding the amplitude values to the nearest available level in the digital representation.
Explanation
Why this works
This answer effectively describes quantisation and its importance in digital signal processing. The question assesses the understanding of how continuous analogue signals are represented in a discrete digital format, which is crucial for signal integrity.
