Design And Implementation Of The Software For Brain Electrical Ward And Analysis System

Brain electronical signals are collected by peripheral equipments before being sent to computer. The latter shows their wave shape in real time manner and uses digital signal processing techniques to analyze them. This paper presents a brain electrical ward and analysis system. It first introduces some interrelated knowledge about brain bio-electric and digital signal processing techniques, before presenting the design and implementation of its software system. The system architecture and function modules (the signal's ward, digital filter and analysis) are discussed in depth. Furthermore, It discusses key techniques used in its signal sampling, filtering and analysis, together with those for color imaging.
