See pictures, ALIAS OFF on FFT, it is totaly useless The picture with alias ON, that is how it looks on a spectrum analyser... also added 3 kc picture, you can see that the other spikes are below the level , as on alias off. Thats why they are not visible on alias off For comparision, added a 3kc from an analog signal generatior |

@ Teneyes, dont use rectangle, use a window, as Hanning or Blackman |
