Hello, I'm Slawekb. I wanted to let you know that I undid one or more of your recent contributions to Fourier transform because it did not appear constructive. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks! Sławomir Biały (talk) 00:15, 21 May 2013 (UTC)
