What Does Discretization Mean?
Discretization is the process of replacing a continuum with a finite set of points. In the context of digital computing, discretization takes place when continuous-time signals, such as audio or video, are reduced to discrete signals. The process of discretization is integral to analog-to-digital conversion. Discretization is related to the term quantization.
Techopedia Explains Discretization
Mathematicians have been busy dividing and quantifying things for thousands of years. They ran into problems from the beginning. The Greek philosopher Aristotle proposed the “dichotomy paradox.” Suppose someone wants to walk home. To get there, one must first walk halfway home. To walk halfway home, one must first walk one-fourth the way home. Since the distance home is infinitely divisible, one must complete an infinite number of tasks to get there. So theoretically, one can never walk home.
