| Apr 14, 2014 at 2:39 | comment | added | xzczd♦ | Your suggestion for changing sample size to 2048 and using a triangle does work (if I've understood it correct). Maybe you can consider improving your answer when you become more familiar with Mathematica, most people here are not familiar with signal processing after all :D | |
| Apr 13, 2014 at 3:54 | comment | added | Alan Campbell | Sorry - like I said, I'm not familiar with Mathematica. However... I'd suggest changing the sample size to 2048: Fast Fourier Transforms in particular prefer multiples of 2 as sample size. Then I'd try a simple [triangle] window: OUT = Data * X / 1024 for X = points 0 to 1023, OUT = Data * (1-X) for points X = 1024 to 2047. | |
