Noise that has a frequency spectrum of predominantly zero power level over all frequencies except for a few narrow bands or spikes. Note: An example of black noise in a facsimile transmission system is the spectrum that might be obtained when scanning a black area in which there are a few random white spots. Thus, in the time domain, a few ...
The noise factor (a linear term) is more often expressed as the noise figure (in decibels) using the conversion: = The noise figure can also be seen as the decrease in signal-to-noise ratio (SNR) caused by passing a signal through a system if the original signal had a noise temperature of 290 K. This is a common way of expressing the noise ...
The noise power from a simple load is equal to kTB, where k is the Boltzmann constant, T is the absolute temperature of the load (for example a resistor), and B is the measurement bandwidth. This makes the noise figure a useful figure of merit for terrestrial systems, where the antenna effective temperature is usually near the standard 290 K ...
List of CB slang. CB slang is the distinctive anti-language, argot, or cant which developed among users of Citizens Band radio (CB), especially truck drivers in the United States during the 1970s and early 1980s. [1] The slang itself is not only cyclical, but also geographical. Through time, certain terms are added or dropped as attitudes ...
The 49er Faithful often refers to fans of the San Francisco 49ers. There are numerous names in conjunction with the 49ers fanbase such as The Niner Gang or the Niner Empire in regards to their success during the 1980s and early 1990s. [1] [2] Due to the large success experienced by the team in winning five Super Bowl titles in the 1980s and ...
SANTA CLARA, Calif. (AP) — The San Francisco 49ers' experiment of bringing in a defensive coordinator from the outside didn't work out, with the team firing Steve Wilks after just one season.
The Tip, sometimes referred to as the Immaculate Deflection, was a play in the 2013 NFC Championship Game in the National Football League (NFL) between the division rivals of the #5 seeded San Francisco 49ers and the #1 seeded Seattle Seahawks.
Noise generator. Zener diode based noise source. A noise generator is a circuit that produces electrical noise (i.e., a random signal). Noise generators are used to test signals for measuring noise figure, frequency response, and other parameters. Noise generators are also used for generating random numbers. [1]
