I have finished two tutorials on noise.

the first one is here:

http://www.fourier-series.com/Noise/index.html

This covers thermal noise, and contains several interactive flash
programs.  included is insight into the thermal noise equation, rms
voltage calculations, examples of correlation and how independent
(uncorrelated) noise adds together. All the programs have extensive
audio explanations.

The second one is here:

http://www.fourier-series.com/Noise/NoiseFigure.html

This covers The basic noise model of an amplifier.  Spectrum analyzer
representations of input signal and noise and output signal and noise
are presented with interactive features to allow the user to modify
signal levels, gain and noise figures of the amplifier.  A full
explanation of the noise factor model and derivation of Friis formula
using interactive programs and audio explanations are provided.

Great site Brent. Thanks for making your easy to understand tutorials. I can see
I'm going to learn a lot from them.
