文摘
- •
The nominal sampling rate is a central technical specification in EEG systems.
- •
The nominal sampling rate determines the Nyquist limit.
- •
Frequency reconstruction above the Nyquist limit causes invalid results.
- •
Approaching the Nyquist limit from below results in data of decreasing validity.
