sir,…I needed the py code of low pass filter. please any one mail me
Hello Vishwanatha,
the filters in GNU Radio are all written in C++, and the mathematical
core functionality is implemented in several versions for different
machines in C with a mixture of SIMD intrinsics (read:
close-to-assembler instructions), because filtering is often a very
computationally expensive part in signal processing and therefore must
be optimized heavily to make systems work in real time.
However, you can use/construct these filters from python. If you want to
see how that would look like, start the gnuradio-companion, connect a
“Null Source”, a “Low Pass Filter”, and a “Null Sink”. Parameterize the
filter block. Save the file, and click on the “generate” button. You’ll
see a message in the box at the bottom like ‘Generating:
“/home/vishwanatha/top_block.py”’. Open that file in a text editor, and
look for the lines that contain low_pass.
Greetings,
Marcus

Also, beside what Marcus said, I recommend reading this page to get the
