Hello, GNURadio offers three different interfaces to design filters from Python code: gnuradio.filter.firdes.xxx, gnuradio.filter.firdes.xxx_2, and gnuradio.filter.optfir.xxx.
The three interfaces use different parameters to specify the filter properties, but the only obvious difference is that the optfir is coded in python and thus not available to be used elsewhere. Which one is recommended to use? Can anyone suggest a reference that explains how the filter taps are computed? In my data analysis code I usually use Butterworth filters. If there is any analogy, how do those map to the filters designed with the above tools? Thanks. Best, Daniele _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
