Abstract
Ένα σχήμα κβάντισης πλάτους για κωδικευτές ομιλίας χαμηλού διφυορρυθμού περιλαμβάνει το πρώτο στάδιο της εξαγωγής ενός διανύσματος φασματικών πληροφοριών από ένα πλαίσιο. Η ενέργεια του διανύσματος κανονικοποιείται (1301) για να δημιουργηθούν παράγοντες απολαβής. Οι παράγοντες απολαβής είναι διαφορικά, διανυσματικά κβαντισμένοι. Οι κανόνι κόποι η μένοι (1301) παράγοντες απολαβής υφίστανται ανομοιόμορφη μειοδειγματοληψία για να δημιουργήσουν ένα διάνυσμα σταθερής διάστασης με στοιχεία που σχετίζονται με μια ομάδα ανομοιόμορφων ζωνών συχνοτήτων. Το διάνυσμα σταθερής διάστασης διαχωρίζεται σε δύο ή περισσότερα υπο-διανύσματα. Τα υπο-διανύσματα είναι διαφορικά κβαντισμένα, για να εκμεταλλευτούν κατά το μέγιστο μια επεξεργασία κλωνοποίησης αρμονικών.
