Noise temperature (antenna) In radio frequency (RF) applications such as radio, radar and telecommunications, noise temperature of an antenna is a measure of the noise power density contributed by the antenna to the overall RF receiver system. It is defined as "the temperature of a resistor having an available thermal noise power per unit ...
Antenna gain-to-noise-temperature ( G/T) is a figure of merit in the characterization of antenna performance, where G is the antenna gain in decibels at the receive frequency, and T is the equivalent noise temperature of the receiving system in kelvins. The receiving system noise temperature is the summation of the antenna noise temperature and ...
A low-noise block downconverter ( LNB) is the receiving device mounted on satellite dishes used for satellite TV reception, which collects the radio waves from the dish and converts them to a signal which is sent through a cable to the receiver inside the building. Also called a low-noise block, [ 1][ 2] low-noise converter ( LNC ), or even low ...
Ku band. Ka band. v. t. e. DVB-T2 is an abbreviation for " Digital Video Broadcasting – Second Generation Terrestrial "; it is the extension of the television standard DVB-T, issued by the consortium DVB, devised for the broadcast transmission of digital terrestrial television. DVB has been standardized by ETSI .
Ghosting (television) In television, a ghost is a replica of the transmitted image, offset in position, that is superimposed on top of the main image. It is often caused when a TV signal travels by two different paths to a receiving antenna, with a slight difference in timing. [ 1]
Full break-in or QSK operation, [ 1][ 2][ 3] is a hardware supported Morse code communications channel turn over communications protocol. So, full break-in is also a duplexing protocol, which facilitates a style of two-way Morse code communications on traditional half-duplex radiotelegraph channels that closely simulates full-duplex channel ...
A line-replaceable unit ( LRU[ 1] ), lower line-replaceable unit ( LLRU ), [citation needed] line-replaceable component ( LRC ), or line-replaceable item ( LRI) [ 2] is a modular component of an airplane, [ 3] ship or spacecraft [ 4] (or any other manufactured device) that is designed to be replaced quickly at an operating location (1st line).
The following is a list of programs that are and will be broadcast on Antenna TV, a general entertainment network owned by the Tribune Broadcasting subsidiary of the Tribune Company, which is designed for digital subchannels of over-the-air broadcast stations in the United States and was launched on January 1, 2011.
