Understanding the technical fundamentals behind operation of EEG equipment should help medical personnel to correctly use all its capabilities and ultimately improve quality of medical care. The basic diagram of the electroencephalograph operation, the types and features of EEG electrodes, the opportunities and limitations of digitally processed bioelectric signals are discussed. A review on the main technical characteristics of EEG equipment and their influence on the quality of the recorded signal is presented.</p></abstract><trans-abstract xml:lang="ru"><p>Целью данной статьи является знакомство медицинских специалистов, занимающихся регистрацией и анализом электроэнцефалографических (ЭЭГ) обследований, с базовыми принципами работы и устройством современного ЭЭГ-регистратора. Понимание технических основ работы ЭЭГ-оборудования должно помочь медицинскому персоналу правильно использовать все его возможности и в конечном итоге повысить качество медицинского обслуживания. В статье рассмотрена принципиальная схема работы электроэнцефалографа, представлены типы применяемых ЭЭГ-электродов и их особенности, возможности и ограничения цифровой обработки биоэлектрических сигналов. Проведен обзор основных технических характеристик ЭЭГ-оборудования, показано их влияние на качество регистрируемого сигнала.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>электроэнцефалография</kwd><kwd>ЭЭГ</kwd><kwd>цифровая фильтрация</kwd><kwd>аналого-цифровой преобразователь</kwd><kwd>электроды</kwd></kwd-group><kwd-group xml:lang="en"><kwd>electroencephalography</kwd><kwd>EEG</kwd><kwd>digital filters</kwd><kwd>analog-to-digital converter</kwd><kwd>electrodes</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Киреев А.В., Ледяева В.С., Резниченко А.А.
