* To reduce noise in the readout of the analog part of this circuit, a common-mode feedback is passed back into the body by the driver right leg circuit, for example, 60Hz noise from nearby A/C power wiring.

* The amplifier board will amplify the signal then the analog to digital converter will digitize the signal and pass the data to the microcontroler board. The microcontroler board is based on the AVR Mega168 which will, further process the signals, and provide an interface to a computer.
