Overview

This is an instrumentation amplifier. It overcomes all the disadvantages of a differential amplifier. It has high input impedance as well as high gain. It amplifies the signal from the sensors on the body before being processed. The differential stage will remove the common voltage or in other words the common 60 Hz noise.
