Abstract

En kvantiserer i en særskilt utførelse er konfigurert for å kvantisere en utjevnet verdi av en inngangsverdi (så som en vektor for linjespektralfrekvenser) for å frembringe en tilsvarende utgangsverdi, idet den utjevnede verdi er basert på en skaleringsfaktor og en kvantiseringsfeil for en tidligere utgangsverdi.
