Mark,
Thanks for your reply. Quick question: the second term isn't b1*x(n-1)?

Sorry, you're right, it should be b1*x(n-1). --Mark

When you init a delay block with a positive value, it creates a
'history' (this is actually also the correct GNU Radio term). This is,
Hi Martin and thanks for your answer.

In other words, where are those 58 spurious bits at the beginning of
the received stream coming from?
Are they just the result of transient behavior inside the sync blocks?
Hello everyone,
I want to simulate file transmission using BPSK modulation, with block
diagram
File Source -- Packet Encoder -- BPSK Mod -- BPSK Demod -- Packet
Decoder -- File Sink
But the result is 0 kB. Then I remove the Encoder-Decoder and Modulation
block.
File Source -- File Sink
Then
Have you set the preamble and access code? The leave blank for automatic
didn't work for me.

But then I was struck by this:
Not sure what you're asking, the command is wrapped from C++ to Python,
and hence the same in both domains (see also
http://gnuradio.org/doc/doxygen/classgr_1_1block.html#acad5d6e62ea885cb77d19f72451581c2).
Also, 0 is the default.

This looks like MATLAB form. If so, the difference equation should be
y(n) = b0*x(n) + b1*x(n) - a1*y(n-1)

Hi list,
I am doing some (polyphase) decimation with GNURadio in C++. I constructed
my filters, I wrote some wrapper, and my script compiles perfectly.
However, I am a bit unclear about declare_sample_delay.
Assume that I have the block: pfb_decimator_ccf_0_5. To set the sample

I've switch back with filters, and I'd like to implement a IIR filters,also

I've see that actually gnuradio is using a direct form I

I implemented my own block that produces a trigger signal when a specific

Hello,
I've been trying to move the fm De-emphasis (an IIR filter, I'm pretty
sure) functionality of the WBFM_Receive block into an FPGA, and I'm a
little confused as to how the taps work.
I'm in fm_emph.py and can see the taps listed as
btaps = [b0, b1]
ataps = [1, a1]
