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 ...
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 ...
The TV Parental Guidelines are a television content rating system in the United States that was first proposed on December 19, 1996, by the United States Congress, the American television industry, and the Federal Communications Commission (FCC). The guidelines went into effect by January 1, 1997, on most major broadcast and cable networks in ...
The antenna noise temperature gives the noise power seen at the output of the antenna. The composite noise temperature of the receiver and transmission line losses represents the noise contribution of the rest of the receiver system. It is calculated as the effective noise that would be present at the antenna input terminals if the receiver ...
Effective radiated power ( ERP ), synonymous with equivalent radiated power, is an IEEE standardized definition of directional radio frequency (RF) power, such as that emitted by a radio transmitter. It is the total power in watts that would have to be radiated by a half-wave dipole antenna to give the same radiation intensity (signal strength ...
The United States pay television content advisory system is a television content rating system developed cooperatively by the American pay television industry; it first went into effect on March 1, 1994, on cable-originated premium channels owned by the system's principal developers, Home Box Office, Inc. and Showtime Networks.

The thyroid system of the thyroid hormones T 3 and T 4 [1] Thyroid hormones are any hormones produced and released by the thyroid gland, namely triiodothyronine (T 3) and thyroxine (T 4). They are tyrosine-based hormones that are primarily responsible for regulation of metabolism. T 3 and T 4 are partially composed of iodine, derived from food. [2]
