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:
