Because this differencing amplifier present high impedance to both inputs, and only uses two amplifiers, 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. 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 $DiffAMP$. 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. We begin by identifying {\fgs} from the components in the circuit.
