I have finished two tutorials on noise.
the first one is here:
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:
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.

------------------------------ PS I posted several times to comp.dsp and sci.electronics.design to get clarity on a few topics contained in this tutorial. So thanks.
