I am doing an EMG as a part of my senior design project. I am currently using an Instrumentation amplifier but my professor suggested using a driven right-leg circuit. I was wondering how using a right-leg circuit would make it better (what are the benefits in filtering, speed, etc)?
He also asked me the following question: What is primary drawback to leaving a patient “floating” (i.e., not connected to the same voltage reference as the op-amp amplifier)? which I don't know how to answer. I thought that it was because the voltage difference could get dangerous, but it doesn't seem plausible.
