Brain wave sensor Low pass filter and amlifier

[wcsperera]

Hi everybody............

I want to make a brain wave detection system with brain wave sensors.

so I need to design a brain wave amplifier circuit and also a Low Pass filter to filter the brain waves from noise signals.(brain wave signal range is from .5 Hz to 30Hz)
so I need some circuit designs of low pass filter circuit and amplifier.

Or please let me know a good website to find those circuit designs .

bye......
