Aggregazione dei criteri
Topics:
- Digitization: sampling, aliasing, quantization, and saturation.
- Spectral analysis: signal as a sum of sinusoids (Fourier Transform), FFT, STFT, wavelets, Welch, multitaper and Hilbert.
- EEG origin and acquisition: from source (synaptic activity of pyramidal cells) to EEG signal on the scalp, international 10-20 system standard, different montages, EEG devices.
- Brain rhythms and uses: delta, theta, alpha, beta and gamma bands, 1/f power "law".
- Artefacts and preprocessing: physiological and non-physiological noise, removed by bad-segment rejection or filtering (see next Lab#1), other methods (to be recalled in next classes).
