Reducing or randomizing the polarization of an electromagnetic wave. Note: Depolarization may be caused by transmission through a nonhomogeneous medium or a depolarizer. 2. Prevention of polarization in an electric cell or battery.
Industry:Telecommunications
Reduction of the noise power level in electrical circuits. 2. The process of automatically reducing the noise output of a receiver during periods when no carrier is being received.
Industry:Telecommunications
Referring to an auxiliary device that usually rests on top of or adjacent to a television receiver and that is used in direct analog or digital satellite transmissions and digital television to be viewed on analog television; a set-top device may convert cable TV or Web signals to a form or format that allows end-user channel selection or interaction via a separate desktop computer or key pad. It may tune channels that the TV does not tune and may include descrambling circuitry. It may also include an electronic program guide. Synonyms set-top box, set-top converter.
Industry:Telecommunications
Referring to or using opto-electronic, electro-optic, or magneto-optic phenomena. Note: Photonic devices include a wide variety of active devices that are used in countless applications in the fields of optical detection and imaging, optical communications systems, direct optical-to-electrical power generation, etc. For example, phtonic devices include, but are not limited to: light-emitting diodes (LEDs,) injection laser diodes (ILDs,) avalanche photodiodes (APDs,) liquid crystal displays (LCDs,) charge-coupled devices (CCDs,) cathode-ray tubes (CRTs,) Kerr cells, Pockels cells, photovoltaic cells, etc.
Industry:Telecommunications
Referring to that portion of the circuitry of a receiver which, with respect to the signal being processed, is chronologically prior to the detection. Note: Predetection signals contain the carrier signal and all modulation, and are basically at radio frequencies.
Industry:Telecommunications
Refers to a telecommunications carrier that receives numbering resources from the NANPA, a Pooling Administrator or another telecommunications carrier. (FCC 00-104, § 52. 15 (f) (2). )
Industry:Telecommunications
Refers to an industry plan to expand substantially the supply of Numbering Plan.
Industry:Telecommunications
Reflection from a rough or irregular surface which does not maintain the integrity of the incident wavefront.
Industry:Telecommunications
Reflection from a smooth surface, such as a mirror, which maintains the integrity of the incident wavefront.
Industry:Telecommunications
Relative to jitter and swim, long-term random variations of the significant instants of a digital signal from their ideal positions. Note 1: Wander variations are those that occur over a period greater than 1 s (second. ) Note 2: Jitter, swim, wander, and drift have increasing periods of variation in that order.
