Thanks martin for your explanation. I modified the dbpsk_loopback.grc
example to where my input sampling frequency is 16khz and instead of
looping back i'm using a uhd sink block with a sampling rate of 256khz.
Looking at the constellation on my spectrum analyzer i'm getting a dbpsk
signal with a

I've been trying to understand what's happening under the hood with the
polyphase filter bank in the generic_mod_demod.py.
Here's what I think is happening, since nfilt=32 which is also used the
sampling rate of the firdes.root_raised_cosine filter means that the
highest rate the polyphase filter
Almohanad,
perhaps the examples in gr-digital/examples/demod are more suitable to
understand the internals.
A couple of notes:
