quantization
/ˌkwɒn.taɪˈzeɪ.ʃən/ IELTSAcademic
noun
Quantization is the process of turning a continuous value into a limited set of values. In science and engineering, it often means rounding a signal or measurement into steps.
- The microphone signal uses quantization.
- The image lost detail after quantization.
- Quantization helps computers store data efficiently.
Adinary Nuance
Quantization is about making something step-like or discrete. It is not the same as rounding in everyday math, because it often refers to a technical process in signals, images, or physics. It is also more specific than simplification, which can mean making something easier in a general way.
