Let's say I have an FFT output that's many, many, bins wide, and I want to compress that information into a narrower display (let's say from 4M bins down to 1024 bins).
My approach has been to sum up each set of [4M/1024] bins, and use that as the final output. But should I be averaging across the bins? That is, should I be taking each 3906bin group from the 4M bin wide spectrum and computing an average across those bins, and stuffing it into the appropriate place in the 1024-wide spectrum, or something else? Seems to me that if I have 4000 1Hz-wide bins, I should sum them to give me the total power in a single bin that "represents" the same amount of bandwidth. But is it more subtle than that? -- Marcus Leech Principal Investigator, Shirleys Bay Radio Astronomy Consortium http://www.sbrac.org _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
