Here i plan to make some code snippets as i go along to maybe help others do what i found very difficult when first learning about Digital Signal processing.
Nothing here will be perfect but the ideas are there to get you started, and then hopefully correct my mistakes!
Basically this is code that takes in IQ samples from an sdr receiver like the rtl dongle.
Idea is to make blocks of code that do the different parts of the dsp chain to receive an SSB and fm signal etc...
Eventually a chirp receiver too if i'm lucky!
More will be added when i get round to it!
See DSP# in the headers for related bits.

Code 'beautifying'! is done with http://hilite.me/
Command line example:
rtl_sdr -p 70 -f 144750000 -s 1024000 - | ./mixer | ./decfir | ./ssbdemod | aplay -c 1 -t raw -r 32000 -f FLOAT_LE -
