GNU Radio

Does anyone have the spectrum-sense implemeted into a wide band fft GUI
display yet? Perhaps a private project they might be willing to share ?
If anyone is working on it let me know if u need any help…

Thank you so much Eric. I’ve another questions can the DAC data
input frequency be slow down to 25kHz? or make the frequency of data
transmitted from FPGA be slow down to 25kHz? How can I make it?

No.

You can however use the interpolator inside the FPGA
(Digital-Up-Converter, DUC) to do part of the work, then interpolate
in software for the remainder.

Please read the USRP FAQ:

and look at this page:

Dave,

I am currently working on my final year project (UG) to implement
exactly what you asked.

Can you help me determine what calculations to do on the fft values
received? There are varying suggestions on a lot of different posts on
the forum, and I am still a bit new to GNU Radio and signal processing.

I will be fully willing to share my work when (if) I am finished :slight_smile:

Cheers,

Yohan
