Definitions for "Quantizer"
An analog-to-digital converter. A device that measures the magnitude of a time varying quantity in multiples of some fixed unit or quantum, at a specified instant or specified repetition rate, and delivers a proportional response that is usually in pulse code or digital form. The amplitude of the response signal is at each instant proportional to the number of quanta measured.
a construct that takes an amplitude-continuous signal and converts it to discrete values that can be reconstructed by a decoder
Detail removal factor (DRF), or the degree of picture blur due to details reduction. Used to allow picture compression.
