Formatted abstract
Electroencephalography is a measurement of the electrical activity of the brain as it appears at the scalp, and is used extensively for diagnosing physical brain disorders. This report investigates the particular requirements of a portable electroencephalographic device capable o f operating in an electromagnetically "noisy" environment. High performance amplifiers are incorporated in an "active electrode" scheme, whereby most of the amplification and common-mode rejection occurs on the patient's head near the electrode site. This is done in order to improve on the performance and large size of EEG machines using conventional "passive electrodes". The EEG unit itself is built around the TMS320C25, a high performance D.S.P. microcontroller. The choice of the TMS320C25 resulted on benchmark comparisons, and other considerations pertaining to portability.
