Hey, just wondering if anyone could point in the right direction on just how to write a block that will write out a feature like instantaneous carrier phase to stdout. I've read all the tutorials on the website and can't seem to find anything that would fit this scenario. I tried going through the code for some of the modulation blocks, but couldn't see how they received the phase data for something like phase modulation.
