Hello..
Am working for my FYP concerning prosthetic arm, so i have to take data from EMG sensors which are on the surface of the body.
The first step of my project is signal conditioning and filtering, so i was searching for circuits concerning signal conditioning and i got the circuit in the following link:
http://biomed.engsoc.org/system/files/images/EMG_Arduino.png
At the write of the figuire they said that :"EMG out voltage is referenced with respect to GND"...My question concerns this point.
What should be the reference point of the out signal!, why its not the body ground, or the 2.5v which is created using the buffer circuit?
Thanks for help
