help required for making acquisition syatem

hi

you have given me the good suggestion.......... but kindly tell me, are you giving me the following idea to implement


As EEg signal is in micro volts , the electrods itself amplify little bit, then from
i think that , strap , what i mean is the electroddes are attached to the Human Scalp with a special Gel.

1) electrodes (straps) > antialiasing low passfilter ( fc= 50hz) > ADC > Amplify ( 10k gain) > microcontroller > Pc

Is this right choice....... show me the clear sequence if any other ..........

2) As i want to work on some desired frequencies in the EEG signal coming from brain, there are also many other artifacts/interferance( EOG ,eye signals ) comeout from brain when we extracting signal( EEG) from brain. Can i implement the ANC filter at place just after extracing signal from Brain ,to subtract the those eye signals.

please help me ....its very imp for me

best regards

Choice 1 is correct, becoz i have implemented this thing myself...
