Sampling and quantization

1. sampling chooses discrete points at which to measure a continuous phenomenon
(which we will also call a signal).

In the case of sound, the sample points are evenly separated in time.
The number of samples taken per unit time or unit space (for image) is called the sampling rate or resolution.

2. quantization, requires that each sample be represented in a fixed number of bits, called sample size or bit depth.
