What is quantisation in the context of digital signals?.
- A.The process of converting a digital signal back to analogue.
- B.The assignment of discrete values to the sampled amplitudes of an analogue signal.
- C.The filtering of noise from a digital signal.
- D.The process of increasing the sampling rate of a signal.
Model answer
What a good answer should say
- The assignment of discrete values to the sampled amplitudes of an analogue signal.
Explanation
Why this works
Quantisation is the process of assigning discrete values to the sampled amplitudes of an analogue signal, which allows for the representation of the signal in a digital format.
