Page: Define - Digitization
- Signals captured from the physical world are translated into digital form by digitization, which involves two processes.
- A signal is digitized when it is subjected to both sampling and quantization, in either order. When an audio signal is sampled, the single dimension of time is carved into discrete intervals.
- When an image is sampled, two-dimensional space is partitioned into small, discrete regions. Quantization assigns an integer to the amplitude of the signal in each interval or region.
