	My guess is that if you shift the black part of the graph by -50, it will form the cat.

		+	I would just like to point out that whoever wrote this article did a fantastic job. No, really, no sarcasm, I'm majoring in electrical engineering, and reading through this page gave me a better understanding of the actual meaning of frequency domain than any of my classes so far. Which doesn't speak much for those classes and speaks a lot for this page. So thanks, I guess? [[Special:Contributions/128.4.80.24\|128.4.80.24]] 15:08, 20 April 2026 (UTC)

	Picking up on shdwdrgn's comment above, how interesting would the Fourier transform of Schroedingers's cat be. I guess it would consist of two overlaid graphs neither of which would be certain until you actually looked at it.[[User:EditorGonk\|EditorGonk]] ([[User talk:EditorGonk\|talk]]) 09:38, 20 July 2018 (UTC)		Picking up on shdwdrgn's comment above, how interesting would the Fourier transform of Schroedingers's cat be.

 I think the transform may be of the movements of various parts of the cat. Cats tend to move their ears and heads a lot, and other parts, less so. What tipped me off is the spike at the tip of the tail. Cats typically twitch the very tip of their tail in a rhythmic fashion.
