Viewing speed and frequency resolution in digital EEG.
This study of viewing speed and frequency resolution of a digital electroencephalograph (EEG) system explains how, in spite of limited video monitor resolution, technological advances permit digital EEG presently to approach paper EEG performance, and in the foreseeable future to exceed it. Analyses of aspects of eye and brain physiology and elements of digital technology reveal how an image traditionally inscribed on paper can be displayed on a video monitor so that viewing and interpretation are as quick and accurate as on paper. Results are compared to standards set by capabilities of the eye and paper EEG.
