For this reason, the related figure of " effective noise temperature " is therefore often used instead of the noise figure for characterizing satellite-communication receivers and low-noise amplifiers.

That will be a concern if the noise figure of the first stage plus that stage's gain ( in decibels ) is not much greater than the noise figure of the second stage.

Then, you can " zoom in " on low-noise topologies and see some tricks to get the noise figure lower . talk ) 20 : 17, 6 September 2009 ( UTC)

At 200 MHz, a noise figure of 2.5 ( or 4 dB ) can be reached with the ECC2000 tube in an optimized " cascode "-circuit with an optimized source impedance.

With noise reduction typical signal-to-noise figures of 70-76 dB with Dolby C, 80-86 dB with Dolby S, and 85-90 dB with dbx could be achieved.

According to Friis's formula, when the gain of the preamplifier is high, the SNR of the final signal is determined by the SNR of the input signal and the noise figure of the preamplifier.

A static white noise figure climbs out of a television and begins walking through the city, encountering a homeless man and breakdancers who are puzzled by her appearance and shocked by her when they try to touch her.

Master created The Noise Figures, about a band, and was indef'd for WP : GROUPNAME . IP editor came back to remove tags I had placed on the article, which I re-added.

However one must check that the noise figure of the second stage is not so high ( or that the gain of the first stage is so low ) that there is SNR degradation due to the second stage anyway.
