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 ...
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]
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 ...
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 .
Pretty much everywhere in the U.S., the hottest part of the day is between 10 a.m. and 6 p.m. The body will gain heat from both the air temperature and solar radiation. The ground also heats up ...
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 ...
Radio-frequency microelectromechanical system. Fig. 1: (a) A capacitive fixed-fixed beam RF MEMS switch, connected in shunt to a CPW line. (b) An ohmic cantilever RF MEMS switch, connected in series to a microstrip line. A radio-frequency microelectromechanical system ( RF MEMS) is a microelectromechanical system with electronic components ...
Media controls on a multimedia keyboard. From top; left to right: skip backward, skip forward, stop, play/pause. Media control symbols are commonly found on both software and physical media players, remote controls, and multimedia keyboards. Their application is described in ISO/IEC 18035. [ 1]
