I got this working. For completeness, I'll answer my own questions and sum
up what I've learned about filtering.
1) You need to call set_history(num_filter_taps) so that block boundaries
are handled smoothly
2) You input samples one at a time to fir_filter_xxf
3) fir_filter_xxf does not store
I have a fundamental misunderstanding of the filter system in gnuradio. I
would appreciate some help. I wrote a simple C++ testbench to help me
figure out what's going on, but it continues to not behave as I expect. I
am using fir_filter_fff with 29 taps that I set. I send an impulse into the

That fixed the problem. Thank you.

Hi all,
Would someone please recommend a good starting point in C++ source code
that demonstrates how one uses the kernel::fir_filter. I started following
the pfb_clock_sync method of implementing it, but then realized this had
been customized a bit for the polyphase approach.
I'm not doing
