I've wrote a diploma thesis (German) about a design modification i have made.
These modifications will allow to measure muscle action potential in particulary to serve as an assistive device (control signal) for people with disabilities. The changes made to the schematic and the filter charateristics will be described in my work. I have also done a lot of test measurments to describe the filter charakteristic much more specific. However, I would like to give my work as free download to the ModularEEG site.
Dear site-admin please mail to: markus(dot)julius(dot)winter(at)gmail(dot)com
and i will send back u my thesis.
