Quantise (Verb)
Meaning 1
Approximate (a signal varying continuously in amplitude) by one whose amplitude is restricted to a prescribed set of discrete values.
Classification
Verbs of thinking, judging, analyzing, doubting.
Examples
- The signal processing technique used was to quantise the input data into a specific range of values to facilitate efficient processing.
- The audio software was configured to quantise the recorded signal to reduce the amount of memory needed for storage.
- In order to implement lossy compression, the raw data were first quantised to limit the amplitude levels.
- By quantising the sampled sound into discrete amplitudes, the noise level can be significantly reduced.
- Quantising the image data into discrete values of brightness enabled it to be more efficiently transmitted over the network.
Synonyms
Hypernyms
Meaning 2
Apply quantum theory to; restrict the number of possible values of (a quantity) or states of (a physical entity or system) so that certain variables can assume only certain discrete magnitudes that are integral multiples of a common factor; "Quantize gravity".

Examples
- To be able to accurately model the system using quantum theory, we would have to quantise the position and momentum to discrete values.
- Their main goal was to quantise space and time so that they could develop a more complete model of the universe.
- Quantising an electromagnetic wave results in particles of energy, also known as photons.
- In order to extend the Standard Model, physicists are now working on a method to quantise gravity and merge it with the other three forces.
- The team made a major breakthrough when they found a way to quantise light in terms of discrete particles rather than continuous waves.
