Because this differencing amplifier present high impedance to both inputs, and only uses two amplifiers,
this is a useful circuit wherever a high impedance differencing amplifier is required.
It represents a circuit that would typically be re-used in many electronic circuits.
It is a configuration that will be used in many electronic circuits.
It would therefore, be desirable to represent this circuit as a {\dc} called say $DiffAMP$.
We begin by identifying functional groups from the components in the circuit.
