This does not happen frequently, but see for example:

post on Signal Processing about wavelets
same post on Quantative Finance about wavelets

I'm sorry for this duplication, but is there a better way to put your post on 2 different sites, without this stupid duplication?

    Don't cross post. The question will be most suitable to one site. Why do you need it on two to begin with? – Oded Jan 17 '14 at 14:38
  • it's maybe 50.00001% more suitable in quant.. if you want, but I'd appreciate contributions of people from dsp – caub Jan 17 '14 at 14:39
  • This is a Quantitative Finances question? How so? – Oded Jan 17 '14 at 14:42
  • @Oded still researching, but wavelet seem interesting to capture patterns, or to compress the number of values in a given time window without much loss (useful for machine learning) – caub Jan 17 '14 at 14:47
  • Seems to me that you would have somewhat different questions to ask on the two sites, wouldn't you? I mean, if there were immunology.stackexchange.com and medicine.stackexchange.com, I would ask a vaccine question on I as "how do naive cd8+ t-cells react to the protein in ..." and on medicine as "how is ... tolerated in children" or something like that - might be getting to the same place, but a different question nonetheless. – Joe Jan 17 '14 at 17:33
  • @Joe yes, I even had to phrase them differently, before I deleted dsp post. but It would have been a plus to be able to submit posts independantly of the site, the sites would just be views of whole SE content. with that I could have posted it with the right tags or 'super-tags' so as both dsp and quant can view and answer on it. – caub Jan 17 '14 at 17:43
  • @cyril That's not how Stack Exchange is intended to work though - each site is intended to be an independent community. – Joe Jan 17 '14 at 17:44
