I am working with a large and long (8 hour) data set. My goal is to
show changes in propagation over time -- in particular, further analysis
of my solar eclipse RF captures.
I want to show the whole 8 hours on a the waterfall without scrolling,
which means I need to write a line to the display every minute or more
(I haven't figured out exactly how many lines the waterfall can display).
The problem is that the data is noisy and displaying one FFT with a long
gap before the next one makes it very hard to discern the signal from
the noise. What I'd like to do is display an average (or rolling
average) of preceding FFTs, not just a snapshot of the most recent one.
The QT Frequency sink allows you to select averaging, but the waterfall
sink does not. Is there a way to have the waterfall use averaging?
Alternatively, is there a block that will average a vector like an FFT?
That's actually probably the best answer for my situation.
Thanks,
John
