WebOne approach could be to perform an FM-detection step (e.g. an atan2() operation followed by a first-order difference) to transform the waveform to measurements of the approximate received frequency versus time. Your FSK signal should then look like a binary-modulated baseband waveform. Then you can apply a nonlinearity to the signal to induce a discrete … WebMar 9, 2024 · Decoding FSK Data with an RTL-SDR and Python. Ian March 9, 2024 1.
