Principles of Digital Communication Systems a Computer Networks is designed as a textbook for digital communication systems, data communication and computer networks, and mobile computing. Part I deals with key topics such as information theory, transmission media, coding, error correction, multiplexing, multiple access, carrier modulation, PSTN, and radio communication. Part II goes on to cover the networking concepts, the ISO/OSI protocol architecture, Ethernet LAN, X.25 protocol, and TCP/IP protocol. Finally, Part III covers mobile computing, including radio paging, cellular mobile, GPS, CTI, unified messaging, and multimedia communication. Helpful summaries, lists of supplementary information, references, and exercises at the end of each chapter make the book a comprehensive resource for anyone pursuing a career in telecommunications and data communication.This technique is known as differential pulse code modulation (DPCM). Another characteristic of the voice signal that can be used is that a sample value can be predicted from past sample values. At the transmitting side, we predict the sample anbsp;...
