Quantisation vs. Quantization — What's the Difference?
By Urooj Arif & Maham Liaqat — Updated on May 14, 2024
Quantisation and quantization refer to the same process of converting a continuous signal into a discrete signal, but differ in spelling; "quantisation" is British English, while "quantization" is American English.

Key Differences
Quantisation is the British English spelling of the term used to describe the process of converting a continuous range of values into a finite range of discrete values. This is common in digital signal processing. On the other hand, quantization is the American English spelling for the same process, reflecting the standard linguistic variations between British and American English.
While quantisation might appear in texts or discussions that adhere to British standards, quantization is typically used in American publications and academic papers. This distinction in spelling does not affect the technical meaning or application of the term but indicates the regional usage.
The choice between quantisation and quantization may also influence related technical terminology in research or educational materials. For example, British educational materials may consistently use "quantisation" along with other British spellings like "analogue" instead of "analog".
In software development and engineering disciplines, the spelling "quantization" might be more prevalent globally due to the influence of American software and international standards which often use American English.
Despite the spelling differences, both terms are understood universally among professionals in fields like digital communications, computing, and electronic engineering. The context in which they are used can sometimes provide clues about the geographical or cultural orientation of the authors or the intended audience.
