Hi,
I need to amplify low amplitude EMG signals from forearm muscles to analize them on an oscilloscope.
I am planning to use an Instrumentation Amplifier to gain the signal by arround 50 times.
Will the attached schematic work to achieve this? Shell I connect someting between the signal electrodes and the Instrumentation Amplifier inputs?
If I connect the reference electrode directly to the batteries (as shown in the schematic), will that be fine?
Any suggestions would be highly appreciated.
