I am sorry, but I think I did not make myself clear: testing random numbers=
=20
post-processing with the statistical tools does NOT give any idea about the=
=20
entropy rate. Thus, all that was calculated is the proper implementation of=
=20
the post-processing operation and not the actual noise source.

What needs to happen is that we need access to raw, unconditioned data from=
=20
the noise source that is analyzed with the statistical methods.

Ciao
