Editing Adaptive predictive coding

'''Adaptive predictive coding''' ('''APC''') is a [[narrowband]] [[Analog-to-digital converter|analog-to-digital conversion]] that uses a one-level or multilevel [[Sampling (signal processing)|sampling system]] in which the value of the [[signal (information theory)|signal]] at each sampling instant is predicted according to a linear function of the past values of the [[Quantization (signal processing)|quantized]] signals.<ref name="Keiser2012">{{cite book|last1=Keiser|first1=Bernard E.|last2=Strange|first2=Eugene|title=Digital Telephony and Network Integration|date=2012|publisher=Springer Science & Business Media|isbn=9781461517870|page=94|url=https://books.google.com/books?id=4E3TBwAAQBAJ&dq=adaptive+predictive+coding+ADC&pg=PA94|access-date=5 April 2018|language=en}}</ref>

APC is related to [[linear predictive coding]] (LPC) in that both use adaptive predictors. However, APC uses fewer prediction coefficients, thus requiring a higher [[sampling rate]] than LPC.
