hi jamshaid;
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
beat regards
