Using a practical, qdown-to-earthq approach, this book explores important areas of communications systems and networking without resorting to advanced mathematics. It introduces the basics using an analogy with daily life whenever possible; extends the basic concepts to illustrate how the system works from a high level; and then fills in details of operation whenever possible. Fundamental Concepts. Electromagnetic Signals. Metallic Media. Optical Media. Antennas. Signal and Fourier Analysis. Amplitude Modulation. Amplitude Modulators and Demodulators. Angle Modulation and Demodulation. Pulse Modulation. Multiplexing. Coding. Digital Modulation. OSI Model. Networking Hardware. Telecommunications. Three Protocols. For technicians who want to keep pace with current developments in the field and for non-technical professionals who need a general understanding of networking or telecommunications hardware.DIFFERENTIAL PULSE CODE MODULATION AND ADAPTIVE DIFFERENTIAL PULSE CODE MODULATION An ... as it is for most voice and some video applications, a lot of redundant information is present in adjacent PCM code words.
