AFSK bitstream filtered (Patreon)

The first generation of the AFSK decoding algorithm had some high frequency noise and even some glitches that could affect the bitstream decoding. It was necessary to introduce some additional form of filtering.

Turns out that if I filter the signal through digital LPF of the baud frequency (in this case 300 Hz for 300 baud) I get clean signal without the glitches.

Stay tuned for updates!
