  2. 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 ...

  3. 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 ...

  4. Noise temperature - Wikipedia

    en.wikipedia.org/wiki/Noise_temperature

    An RF receiver system is typically made up of an antenna and a receiver, and the transmission line(s) that connect the two together. Each of these is a source of additive noise . The additive noise in a receiving system can be of thermal origin ( thermal noise ) or can be from other external or internal noise-generating processes.

    en.wikipedia.org/wiki/Owned-and-operated...

    In the United States, owned-and-operated television stations (frequently abbreviated as O&Os) constitute only a portion of their parent television networks ' station bodies, due to ownership limits imposed by the Federal Communications Commission (FCC). Currently, the total number of television stations owned by any company (including a ...

  7. Noise figure - Wikipedia

    en.wikipedia.org/wiki/Noise_figure

    The noise figure is the difference in decibel (dB) between the noise output of the actual receiver to the noise output of an "ideal" receiver with the same overall gain and bandwidth when the receivers are connected to matched sources at the standard noise temperature T0 (usually 290 K).

    Currently, Spectrum customers get cable TV access through what’s called a “set top box,” or cable receiver box. Those boxes get you access to all of the Spectrum shows you subscribe to and ...

  9. Optical Carrier transmission rates - Wikipedia

    en.wikipedia.org/wiki/Optical_Carrier...

    Optical Carrier transmission rates are a standardized set of specifications of transmission bandwidth for digital signals that can be carried on Synchronous Optical Networking (SONET) fiber optic networks. [ 1] Transmission rates are defined by rate of the bitstream of the digital signal and are designated by hyphenation of the acronym OC and ...
