I have a couple of questions about the GnuRadio QT GUI Frequency Sink Block , which allows you to specify FFT size and update rate.
* My understanding it that , when it is time go compute another spectrum according to the update rate setting, the block will grab the most recent N samples to do so; so that any IQ data coming in between updates is dropped on the floor. Right? * The blocks output is a graphical plot. If anything in the system causes the graphics to really slow down, will it also slow down the spectrum update rate to less than the configured setting? The above are Gnuradio questions, not usrp questions, so if this is the wrong place for them I apologize. rb
