Hi Gerhard, if I interpret your interpretation correctly, you assign a 1 to "long period", and a 0 to a "short period"? That would be an FSK inside an FSK; such systems exist (often for things like put data on a readily available FM modulator), but from the picture of your signal it's hard to tell.
What do you know about your signal? Best regards, Marcus On 28.05.2016 21:21, Gerhard wrote: > Hello! > > I want to decode a signal that slightly varies in Frequency.
