B All natural background noise?

  1. Jun 23, 2016 #1
    I am trying to find the source of this diagram which came out of some old notes (not mine) I found uploaded on the web.

    the referencing is not clear.

    it seems a great diagram and I would like to find a similar one like it (or better graphics) if not the original, and some explanatory text.

    I have never seen natural noise all plotted out neat like this, pretty awesome.

    K, most likely from Kraus antenna book. I will follow it up.

    Good catch, thanks.
