Dear All,
I'm new to Gnu Radio. I looked carefully to the doc and tutorials but could not find any simple answer to my problem.
I have a radio signal from which I'm able to visualize the FFT in GNU Radio Companion.
Now
I would like to save the FFT (more exactly the magnitude squared, or
the spectrum) accumulated over a given period of time (the average over
time) into a file.
I found the following blocks in GRC that seem to be helpful:
- stream to vector
- FFT
- complex to mag
- file sink
However I did not manage to save any accumulated spectrum...
Any help (eg a woking example) would be very welcome!
Thanks in advance.
