Quantization

The process of selecting whole numbers to represent the voltage level of each sample.

The A/D converter must select a whole number that is closest to the signal level at the instant it is sampled. This produces small rounding errors that cause distortion.

Quantization distortion increases at lower levels because the signal is using a smaller portion of the available dynamic range, so any errors are a greater percentage of the signal.
