2007/6/13, Abram Young <[EMAIL PROTECTED]>:
Hi,
I'm a recent gnuradio/python user (newbie) and have played with the python
pieces and USRP as far as time will allow for now. I can write my own
program to record A/D streams to disk, but that's about it. I'm using
Octave to read in and plot the streams then.
I'd like to either modify the usrp_fft.py code, or add the fft_sink call
to my own .py (preferred) and output to stdout. Specifically, I need to
access the data from fft_sink to find the maximum, and output it's
frequency/value. How do I do this?
You can either use the gr.max_xx or gr.argmax_xi blocks that are
available in trunk to get the maximum value or the argument of the
maximum value from the FFT.
Or you can just sink the signal to a vector sink, and process the
recorded signal with numpy/scipy or octave/matlab if that is your cup
of tea.
