I am designing a device with ECG and EMG amplifier. Since I am using DRL on both of them, I want to know what is the effect if I have two DRL feedbacks, one on right leg for ECG and other on the limb for EMG. Since these are two different feedbacks, I think it will be a problem. How can this one be solved. Or, shall I remove DRL for EMG and connect the reference instead instead? What could be the best solution?
