Quantize is a technical term used in the field of digital signal processing, which refers to the process of converting a continuous quantity or waveform into a discrete representation. Some synonyms of quantize include digitize, discretize, sample, and round. Digitizing describes the process of converting an analog signal into a digital representation. Discretizing means dividing something into discrete or separate parts. Sampling is the process of measuring the value of a signal at specific points in time. Rounding refers to the process of approximating a decimal value to the nearest integer value. All these synonyms are closely related to the process of quantizing and are often used interchangeably in technical writing.
