Abstract
A circuit is described which, in conjunction with an analog filter, greatly increases the accuracy of the identification of EEG alpha activity. With minor modifications, the same circuit may be used to identify other EEG frequency bands. Construction is simplified through the use of integrated circuits. A functional description and circuit details are given.Keywords
