Guideline 1: Minimum Technical Requirements for Performing Clinical EEG correct answer: Digital equipment has many advantages over analog equip- ment and is now used for EEG in most facilities. Some recommendations in this guideline have changed to reflect the greater functionality of digital equipment, including the ability to record good quality signal with nontraditional electrodes and slightly higher impedances. The list of basic patient information has been expanded to include more factors...
