ABSTRACT.During the past ten years, computer technology has made its way into many facets of our lives. Until recently, however, computer technology had managed to elude the practice of clinical EEG. As instrument manufacturers increasingly use computerized systems and modular software package designs in their new product lines, the specialty of EEG is going to experience many benefits not offered by conventional EEG instruments. This paper addresses the basic concepts of digital EEG technology and the differences between digital and conventional instrumentation.
