I'm new to working on gnuradio (experience operating it with a usrp but not developing for it) so hopefully someone can help me out a bit here.
I want to write a module to compare different signals, looking for differences in a few factors by passing some signal features over time to a python program. To do this, should I write a sync block in C++ (or possibly multiple sync blocks) that will keep a long history and output a vector of the amalgamated features at some point to a python top block for evaluation? For instance, I want to read the instantaneous phase, frequency, and amplitude of a signal at the same time and output each of these to a python app, where I do some more work and then stop. I have looked through the gnuradio utilities and don't see many blocks/utilities that I could use just to read something like instantaneous phase and pass that along. Any help is appreciated, thanks.
