Quantification (signal)
En traitement des signaux, la quantification est le procédé qui permet d'approcher un signal continu par les valeurs d'un ensemble discret d'assez petite taille. On parle aussi de quantification pour approcher un signal à valeurs dans un ensemble discret de grande taille par un ensemble plus restreint. L'application la plus courante de la quantification est la conversion analogique-numérique mais elle doit le développement de sa théorie aux problèmes de quantification pour la compression de signaux audio ou .
Bandlimiting
Bandlimiting refers to a process which reduces the energy of a signal to an acceptably low level outside of a desired frequency range. Bandlimiting is an essential part of many applications in signal processing and communications. Examples include controlling interference between radio frequency communications signals, and managing aliasing distortion associated with sampling for digital signal processing. A bandlimited signal is, strictly speaking, a signal with zero energy outside of a defined frequency range.
