The Fiber Optics Illustrated Dictionary - Part 4 fills a gap in the literature by providing instructors, hobbyists, and top-level engineers with an accessible, current reference. From the author of the best-selling Telecommunications Illustrated Dictionary, this comprehensive reference includes fundamental physics, basic technical information for fiber splicing, installation, maintenance, and repair, and follow-up information for communications and other professionals using fiber optic components. Well-balanced, well-researched, and extensively cross-referenced, it also includes hundreds of photographs, charts, and diagrams that clarify the more complex ideas and put simpler ideas into their applications context | Fiber Optics Illustrated Dictionary transmission. The idea was to use preceding samples to continuously predict subsequent speech samples to compare them and transmit the residual prediction error. At the receiving end the same prediction algorithm and information about the residual were used to reconstruct the samples. The result was more natural sounding speech. The approach was not limited to speech encoding it was generalizable to audio and visual signal processing tasks such as sound or image compression. APC may be used with other types of predictive coding as in still image compression in which different characteristics of an image are processed through different coding schemes for maximum compression. APC is frequently used for speech and image digitization and is usefill in environments where data compression lowers bandwidth or increases the speed of network transmissions. See Shroeder Manfred. adaptive routing A system of dynamic network routing that utilizes intelligence in addition to information in routing tables to establish best routes fastest routes or alternate routes in the case of obstructions in the usual paths. Adaptive routing is intended to help optimize routing in a system that may change in its overall scope or topology or in its use characteristics at a given point in time. Optimization through adaptive routing is not always measured in terms of speed. In a network in which machines come and go . a large distributed network like the Internet adaptive routing may be assessed in terms of reliable delivery of data in a constantly changing environment for example. See hop-by-hop routing. adaptor A person who physically or otherwise directly modifies a system component or instrument to perform a different function or to perform a function or set of functions in a different way. See adapter adopter. ADAS See Automated Directory Assistance Service. ADB See Apple Desktop Bus. ADC A DC 1. analog-to-digital converter. A technology that is .
