Hi Henry,

I have a similar desire to learn. If you're interested in studying a
thing, we are building an EEG Arduino shield [0] in the Neurohacking
group. It inspires me that we are able to build circuits with such small
and precise analogue filters to amplify the brain signal. I have an
intuitive belief that low signal to noise ratio demands much thought
into layout and design. I would like to transform that belief into an
understanding of the maths and physics involved. I am very interested in
studying the analogue filters and their layout on this board.
