I should add to my last posting:

Shannon did prove that the capacity of a Gaussian channel with feedback and
without feedback is the SAME, iof the noise is white, i.e., its power spectral
density is constant over the bandwith. It remains to show that the same is
true or that capacity does not increase much when feedback is introduced, and
for other power spectral densities. This is the conjecture made by Prof. Cover
at Stanford.
