Using gnuradio how can I determine fsk_deviation_hz? I'm new on rf analisys and I can't find how to retrieve that value starting from the signal... What i have to look?

I'm voting to close this question as off-topic because not a programming question. Also, the frequency deviation in FSK is really not a complicated topic if you understand the basics of FSK, so please get a digital communications entry-level textbook and read up on FSK. – Marcus Müller Nov 22 '17 at 20:52

Maybe question was not clear... I know what fsk deviation is, I would like to know if there's a smart way to evaluate that using gnuradio (maybe an existent or 3rd party block).. Having to check many samples i'm trying to automatize that... Thanks anyway – fraschizzato Nov 22 '17 at 21:30

You need to build a frequency estimator. But then, you probably wouldn't need to explicitly have the FSK deviation, because the freq estimator could already serve as demod. – Marcus Müller Nov 22 '17 at 21:43

That is, given you need an online deviation estimate. Usually, you just look at a spectrum estimate offline and infer from that manually. – Marcus Müller Nov 22 '17 at 22:40
