EEG Acquisition Chain
Interactive simulator of the physical EEG signal path and sensor-based artifact compensation.
EEG spectrogram with a 16 by 16 skull projection, noise-density plot, and signal-chain equations
- Chain. Cortex → volume conduction → electrode–skin impedance → AFE/PGA → AMUX/ADC, with linked waveforms, spectrograms, complex transfer functions, and noise budgets.
- Compensation. Force, displacement, impedance, optical state, and neighboring channels drive a deliberately simple estimator, scored against simulator ground truth through sensor ablations.
- Boundary. Observable nuisance can be subtracted; volume-conduction loss, clipping, aliasing, and electronics noise cannot be reconstructed.
