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?

Hello! I want to decode a signal that slightly varies in Frequency. Therefore I used "Quadrature Demod" block. After this, its waveform looks like the appended image "baudline-waveform.jpg". Although it's a bit fuzzy I already can decode it with my eyes. Have a look at the appended picture "decoded-signal.jpg". My Questions: * How do I decode the signal to ones and zeros? * Is the signal O.K. the way I demodulated it, or is it to fuzzy? Any help is appreciated! Cheers Gerhard
