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 ...
Campville Defect Detector readout. A defect detector would sound like this: (This was the read out of CSX train Q452-05 by the Campville Defect Detector on April 6, 2019. The defect detector is located at Campville, Florida, on the CSX Wildwood Subdivision.) CSX EQUIPMENT DEFECT DETECTOR. MILEPOST 7-0-0-POINT-1. NO DEFECTS. NO DEFECTS. TOTAL ...
A crystal radio receiver, also called a crystal set, is a simple radio receiver, popular in the early days of radio. It uses only the power of the received radio signal to produce sound, needing no external power. It is named for its most important component, a crystal detector, originally made from a piece of crystalline mineral such as galena ...
The Reel Top 40 Radio Repository, sometimes called REELRADIO, is a virtual museum of radio broadcasts, primarily airchecks from the "Top 40" era of radio in North America. The archives are available by streaming. Established in 1996 as the first online airchecks archive, it was transferred to a dedicated not-for-profit organization, REELRADIO ...

The cooling is necessary for the operation of the semiconductor materials used. Typical operating temperatures range from 4 K (−269 °C) to just below room temperature, depending on the detector technology. Most modern cooled detectors operate in the 60 Kelvin (K) to 100 K range (-213 to -173 °C), depending on type and performance level.
In electronics, noise temperature is one way of expressing the level of available noise power introduced by a component or source. The power spectral density of the noise is expressed in terms of the temperature (in kelvins) that would produce that level of Johnson–Nyquist noise, thus: where: P N {\displaystyle P_ {\text {N}}}
The cost of the surgery can be significant. According to ASPS, the average cost of a surgeon’s fee for cosmetic breast reduction is $6,771. Additional fees may include anesthesia and hospital or ...
