Hi everyone !
Regarding Palm coupled EEG or standalone EEG, I have the following idea:
there are now so called PSoC (programmable system on a chip) microcontrollers,
e.g. from Cypress. They include analog modules with switched capacitor
structures. These can be used for analog filters. Therefore, instead of
digital filtering, these devices would allow analog filtering. But they would
still be digitally reconfigurable and controllable. The signal processing for
most biofeedback systems could therefore be solved by using such a chip.
Disadvantage: only bandpass filters, no true FFT.
