  2. Noise temperature (antenna) - Wikipedia

    en.wikipedia.org/wiki/Noise_temperature_(antenna)

    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 ...

  3. Antenna gain-to-noise-temperature - Wikipedia

    en.wikipedia.org/wiki/Antenna_gain-to-noise...

    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 ...

  4. Eye pattern - Wikipedia

    en.wikipedia.org/wiki/Eye_pattern

    In telecommunication, an eye pattern, also known as an eye diagram, is an oscilloscope display in which a digital signal from a receiver is repetitively sampled and applied to the vertical input ( y-axis ), while the data rate is used to trigger the horizontal sweep ( x-axis ). It is so called because, for several types of coding, the pattern ...

  5. Low-noise block downconverter - Wikipedia

    en.wikipedia.org/wiki/Low-noise_block_downconverter

    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 ...

    en.wikipedia.org/wiki/ATSC_standards

    t. e. Advanced Television Systems Committee ( ATSC) standards are an International set of standards for broadcast and digital television transmission over terrestrial, cable and satellite networks. It is largely a replacement for the analog NTSC standard and, like that standard, is used mostly in the United States, Mexico, Canada, South Korea ...

    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]

  9. Television antenna - Wikipedia

    en.wikipedia.org/wiki/Television_antenna

    A television antenna, also called a television aerial (in British English ), is an antenna specifically designed for use with a television receiver (TV) to receive terrestrial over-the-air (OTA) broadcast television signals from a television station. Terrestrial television is broadcast on frequencies from about 47 to 250 MHz in the very high ...
