Simple, but fucks what little I know about signals. There's one question I'm just unable to answer: how such a signal should be digitized not to lose information? It's not just a matter of "max freq is f, db range is x, you need to sample at 2f at k*log(x) bits" since it's a binary signal where the information is encoded in high resolution timings...
