Does firdes.band_pass *always* produce a working filter? I assume that it uses the Remez exchange algorithm to do its work. What happens if you ask for for a filter that can't be realized?
Right now, I have a bunch of filters that are roughly 200Hz wide, and I'd asked firdes.band_pass to produce filters that had 5Hz transition bands. The result was a CPU hog, so I backed-off to transition bands that are roughly 20Hz wide. Less CPU usage now. Is there any way to tell if firdes.band_pass produced a correctly "converged" filter? -- 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
