✦ Synopsis

This paper describes a novel mimetic technique of using frequency domain approach and digital filters for automatic generation of EEG reports. Dtgittzed EEG data files, transported on a cartridge, have been used for the analysis. The signals are liltercd for alpha, beta, theta and delta bands with digital bandpass filters of fourth-order. cascaded, Butterworth. infinite impulse response (IIR) type. The maximum amplitude. mean frequency continuity index and degree of asymmetry have been computed for a given EEG trequency oand. Finally. searches for the presence of artifacts (eye movement or muscle artifacts) in the EEG record\ have been made.
