Abstract :
The design and construction of an analog tracking filter to monitor EEG waves, is presented. The design is based on a constant bandwidth passive tuned bandpass filter and a feedback control unit to automatically tune the filter to the correct frequency. The control voltage of the feedback loop indicates the frequency of the input EEG signal. The filter tends to tune to the frequency where there is maximum energy.
