[Discuss-gnuradio] where is AM(FM) modulation code?

2008-09-24 Thread jiangfan shi
Hi, I found the am_demod.py and fm_demod.py in the blks2impl folder, but I could not find the source code for AM modulation and FM modulation? Can anyone give me a hint for finding both of modulations (AM modulation and FM modulation)? Thanks very much for your help. Jiangfan

Hi, All, I looked through the gr_chunks_to_symbols_bc code, my understanding is that it handles a two-dimension array. Based on the following work() function, my understanding is that each input_items[m] is a list of chunk (called stream in this function), and the input_items itself is a list of

Hello, I am a newbie for the gnu radio. I am trying to transfer some modulation/demodulation into Java, which can be used in my PhD experiments. My question is that I could not find gr_packed_to_unpacked_bb.cc file in my downloaded truck of the gnuradio. But I do see the explanation in the doxyge
