Hi all! A have a little probleme with FFT.
I use the GRC without USRP. I would like to messeaure a triangle signal, but i never becam the right effect. I attached the picture about the measuring. The problem are the followed: I don't why but, i have allways a peak at 0Hz. - Independent from the type of signal On the picture i messaure a triangle, but the next peak in the FFT failed at 12kHz. Attached picture: http://img8.imageshack.us/img8/5620/messung5.png Have you any Idea?
