How do I create a complex Gaussian joint PDF plot (example figure)?
You are confusing the "time domain" with the "frequency domain". The term "white noise" is based on an analogy with white light. The latter term means that all optical frequency components >>within the visible range<< are present with nominally equal intensity. When we refer to "white noise", again the meaning is context dependent. In the context of acoustics, it might mean that all frequency components in a band from 20 Hz to perhaps 15 kHz are present with equal spectral density, that frequency range being what human ears typically span. All of the above instances relate to the "frequency domain." But when we are looking at, for example, noise voltages, we may be interested in the "time domain" statistics. For example, what is the probability that the instantaneous noise voltage exceeds, say, 11.5 microvolts. In the time domain, "random" noise voltages tend to have a so-called "normal" or Gaussian amplitude distribution. This is especially likely to be true if the observed voltage is some kind of summation of >many< individual random electron motions. In that situation, a statistical concept called "the central limit theorem" becomes relevant. (can be googled!)
PDF documents can be cumbersome to edit, especially when you need to change the text or sign a form. However, working with PDFs is made beyond-easy and highly productive with the right tool.
How to Create PDF with minimal effort on your side:
- Add the document you want to edit — choose any convenient way to do so.
- Type, replace, or delete text anywhere in your PDF.
- Improve your text’s clarity by annotating it: add sticky notes, comments, or text blogs; black out or highlight the text.
- Add fillable fields (name, date, signature, formulas, etc.) to collect information or signatures from the receiving parties quickly.
- Assign each field to a specific recipient and set the filling order as you Create PDF.
- Prevent third parties from claiming credit for your document by adding a watermark.
- Password-protect your PDF with sensitive information.
- Notarize documents online or submit your reports.
- Save the completed document in any format you need.
The solution offers a vast space for experiments. Give it a try now and see for yourself. Create PDF with ease and take advantage of the whole suite of editing features.

There's just no way to do it at all, realistically. There are two reasons I can see as to why you're trying to do that: I could be totally wrong, of course. It might still work...
