Noise figure (NF) and noise factor (F) are figures of merit that indicate degradation of the signal-to-noise ratio (SNR) that is caused by components in...

parallel noise is associated with the fluctuations of the APD bulk and surface dark currents. Another noise source is the excess noise factor, ENF. It...

calculate the signal-to-noise ratio of a multistage amplifier. One relates to noise factor while the other relates to noise temperature. Friis's formula...

internal thermally produced noise. These types of receivers are referred to as cryogenic receivers. Noise figure (NF) is noise factor (F) expressed in decibels...

in the definition of a system's noise factor or noise figure. The noise factor specifies the increase in noise power (referred to the input of an amplifier)...

connected to a noise-free network or amplifier, as that of the actual network or amplifier connected to a noise-free source. If F is the noise factor numeric...

key electrical parameters for an RF chain are system gain, noise figure (or noise factor) and overload level.: 2  Other important parameters, related...

Johnson–Nyquist noise (thermal noise, Johnson noise, or Nyquist noise) is the electronic noise generated by the thermal agitation of the charge carriers...

of amplifiers. The Y-factor method is a common measurement technique for this purpose. By using a noise diode, the output noise of an amplifier is measured...

\;F\;\cdot \;SNR_{o}} where F {\displaystyle F} = noise factor N i {\displaystyle N_{i}} = input noise power S N R o {\displaystyle SNR_{o}} = required...

may use different factors or bases for the logarithm, depending on the context and application. One definition of signal-to-noise ratio is the ratio...

Internet, there was very little background noise but with its commercialization in the 1990s the noise factor became a permanent feature. The Conficker...

tests in the region of 8 kHz-16 kHz. Some environmental factors, such as ototoxic medication and noise exposure, appear to be more detrimental to high frequency...

resulted in "compounded noise." This involves combining a few noise factors to create two levels in the outer array: First, noise factors that drive output...

Pink noise, 1⁄f noise, fractional noise or fractal noise is a signal or process with a frequency spectrum such that the power spectral density (power...

the loaded quality factor, fm is the offset from the output frequency (Hz), fc is the 1/f corner frequency, F is the noise factor of the amplifier, k...

Shot noise or Poisson noise is a type of noise which can be modeled by a Poisson process. In electronics shot noise originates from the discrete nature...

less than a factor of two (a 3 dB noise figure (NF)). Although LNAs are primarily concerned with weak signals that are just above the noise floor, they...

Noise pollution, or sound pollution, is the propagation of noise or sound with ranging impacts on the activity of human or animal life, most of which are...
