issue with fsk demodulation about urh HOT 4 CLOSED

Did you try increasing the error tolerance?

from urh.

I tried different value (1,2,3...) But without success. Should I use much larger value? Do you have documentation how the error tolerance work? But if you looks at the graphic the signal look very clean so I doubt it need error correction.

Thank for your support

Actually your signal does not look clean at all. I assume that you see many fallbacks to the center if you zoom in far enough. As @jopohl said, you either have to increase the error tolerance or apply a better filter or record the signal in a more clean way.

got it I understand what you meant. I used the band pass filter and it fixed it. Thank you for your help.
