Hi Andrew!

Thanks for the comment and the interest.

The sources are at the footer of the article:

«If you search for the sources, you can read the Dan Sturtervant IEEE article, or watch his video on YouTube explaining all of this with great detail.»

Sadly, the article is only for paid subscriptors of researchers, but I am sure that you can get a copy elsewhere. But also it is interesting to check the citations of that article.

Thanks! Sorry if I was not clear enough.
