ATIS is the leading technical planning and standards development organization committed to the rapid development of global, market-driven standards for the information, entertainment and communications industry.
The brightness of an area subjectively judged relative to the brightness of a similarly illuminated area that appears to be white or highly transmitting.
Industry:Telecommunications
The branch of technology devoted to the design, development, and application of communications facilities used specifically for control purposes, such as for controlling (a) industrial processes, (b) movement of resources, (c) electric power generation, distribution, and utilization, (d) communications networks, and (e) transportation systems.
Industry:Telecommunications
The branch of technology devoted to (a) the study and application of data and the processing thereof; i.e., the automatic acquisition, storage, manipulation (including transformation,) management, movement, control, display, switching, interchange, transmission or reception of data, and (b) the development and use of the hardware, software, firmware, and procedures associated with this processing.
Industry:Telecommunications
The branch of science devoted to the transmission, reception, and reproduction of sounds, such as speech and tones that represent digits for signaling. Note 1: Transmission may be via various media, such as wire, optical fibers, or radio. Note 2: Analog representations of sounds may be digitized, transmitted, and, on reception, converted back to analog form. Note 3: "Telephony" originally entailed only the transmission of voice and voice-frequency data. Currently, it includes new services, such as the transmission of graphics information. 2. A form of telecommunication set up for the transmission of speech or, in some cases, other sounds.
Industry:Telecommunications
The branch of science devoted to the study and measurement of the interaction of waves, such as electromagnetic waves and acoustic waves. Note 1: The interaction of the waves can produce various spatial-, time-, and frequency-domain energy distribution patterns. Note 2: Interferometric techniques are used to measure refractive index profiles, e.g., those of the preforms from which optical fibers are drawn, and to sense and measure physical variables, such as displacement (distance,) temperature, pressure, and magnetic fields.
Industry:Telecommunications
The branch of science and technology that is devoted to the production, transmission, control, processing, transformation, reception, and effects of sound, longitudinal waves, particularly as vibration, pressure, or elastic waves and shock phenomena in material media.
Industry:Telecommunications
The branch of optics that treats light propagation as a wave phenomenon rather than a ray phenomenon, as in geometric optics.
Industry:Telecommunications
The branch of optics that describes light propagation in terms of rays. Note 1: Rays are bent at the interface between two dissimilar media, and may be curved in a medium in which the refractive index is a function of position. Note 2: The ray in geometric optics is perpendicular to the wavefront in physical optics. Synonym ray optics.
Industry:Telecommunications
The branch of optical technology concerned with the transmission of light through fibers made of transparent materials such as glasses and plastics. Note 1: Telecommunications applications of fiber optics use flexible low-loss fibers, using a single fiber per optical path. Present-day plastic fibers have losses that are too high for telecommunications applications. Note 2: Various industrial and medical applications of fiber optics, such as endoscopes, use flexible fiber bundles in which individual fibers are spatially aligned, permitting optical relay of an image. Note 3: Some specialized industrial applications use rigid (fused) aligned fiber bundles for image transfer; such as in the fiber optics faceplates used on some cathode ray rubes (CRTs) to "flatten" the image.
Industry:Telecommunications
The boundary that separates a network section from the adjacent circuit section, or separates an access circuit section from the adjacent DTE (data terminal equipment. ) Synonym boundary.
