I have an FSK signal that I want to reverse engineer. I know...
a) the two frequencies involved (scope/spectrum analyser tells me that)
b) the bit time (scope)
c) the sort of data the signal carries
Rather than build a hardware decoder I'm wondering if anyone has used and can recommend a software solution.
I'm thinking that I clean up the signal and then digitise is using a logic analyser giving me a file of sampled data at 2*Nyquist (at least). What I'd like to do is feed that into 'something' to extract the bit stream.
