Thank you, Tom!
I will try it on my Raspi soon.

I think I see the pro
As I said, I cannot design a filter with a sampling frequency below 1e6.
The Python script I posted (where f_s = 1e3) does NOT work! But if I
change f_s to 1e6 it works and gives me the gigantic filter.

You can find my sample Python script two posts earlier.

Hi Tom,
what you are writing is completely right. Simply increasing the sampling
frequency will result in a more complex filter.
Nevertheless the firdes.low_pass function does NOT want to calculate the
101-tap-filter. But it DOES calculate the 11-tap-filter. Really
strange. So this might not

Hello again,
meanwhile I got some more information about the error.
It occurs when returning the taps from the firdes::low_pass function.
But ONLY under some conditions.
I wrote a simple script which is NOT working and giving the error

Good evening Marcus,
thanks for your fast response.
In my sources firdes.cc:136 is

I cloned them from the git repository. Here is the source of the
trouble-making file:

Maybe you have
I pulled and compiled the latest gnuradio yesterday on an intel machine.
My project uses the rational resampler as well and I am having no problems.

Hi Frederik, hi rest,
this is an interesting error. You might want to report it.
The interesting part of your backtrace is
#8 ~vector (this=0xbee7c59c, __in_chrg=)
at /usr/include/c++/4.6/bits/stl_vector.h:350
#9 gr::filter::firdes::low_pass (gain=,

Hi everyone,
I am using the latest GNU Radio version compiled and running on a
Raspberry Pi with Raspbian Wheezy.
Most of the blocks seem to work. But the Rational Resampler makes problems.
Here is my sample python script generated by GNU Radio Companion:
