Filterbanks


#1

Is there a usable filterbank block currently available in Gnu Radio?

If I wanted to break up a 4Mhz input bandwidth into a plenitude of
narrower channels, farming out
the processing of these narrower channels to other processors, is
there a block that can help get
me started?

I’m thinking of doing a distributed SETI-search engine this way

We have the analysis_filterbank and the synthesis_filterbank, which can
be found in

gnuradio-core/src/python/gnuradio/blksimpl/filterbank.py

and the ayfabtu.py example shows the basic usage.

Yes,

See gnuradio-core/src/python/gnuradio/blksimpl/filterbank.py

There’s a somewhat bit-rotted examples that uses this.
See gnuradio-examples/python/usrp/ayfabtu.py.
