520 |a"The objective of this research is to develop an interface between"telephone standard" PCM systems and Delta modulation systems. Although PCM is a well characterized standard and low cost PCM codecs are now available, Delta modulation is often used where the available bit rate is low or when a noisy channel introduces frequent bit errors. Both coding formats are used in existing systems"--Introduction, page 3.
