Re: [Discuss-gnuradio] WX GUI FFT sink block issues

Wow, it's amazing that that flowgraph even works at all.
4.8 Gsps is an astronomical sample rate and shows
a basic misunderstanding of how GnuRadio and SDR
work.

GnuRadio is a baseband processing architecture. Your
SDR hardware (USRP, bladeRF, hackRF, etc.) is responsible
for translating the baseband to a radio frequency, not
GnuRadio.

I've attached a more reasonable flowgraph for you to experiment
with. Try some different parameters in the signal source and
note the effects. You can download the flowgraph here:

For the last question,i have added a screen shot..see that there is no signal in my time plot,just a line..
