As we know Duffing equation works only in analog domain. But in practice it's completely usefulness, we need digital filter which works like Duffing. I try to do it with Volterra series.
Test cases: learn on noise, learn on signal, learn on signal and noise. And results: give signal to learned by signal, give noise to learned by noise (now I realize what I don't need this case) and give signal and noise to last case. And some picture
Looks like Volterra series learned with signal implement output signal pretty good. TODO investigate noise issue in this case.
And files: signal+noise, signal, noise.
