[Discuss-gnuradio] screen shot (adc_fft)

[Eric Blossom]

Hi Folks,

I've attached an screen shot of one of the GNU Radio example
applications running.  What you're looking at is the FFT of the IF
signal sucked out of an conventional FM radio.  The actual IF is at
about 11.4 MHz, but is aliased down to 8.6 MHz due to the 20 MHz
sampling rate.

This is running in real time with 20M samples/second input.  The
display is being updated 30 times / second.  This application is
burning about 12% of a 1.7 GHz P4.
