		<description><![CDATA[When designing a differential amplifier, part of the art is to manage the errors affecting the precision of the circuit.  In The Differential Amplifier Common-Mode Error - Part 1 of this presentation I discussed the common-mode error of a differential amplifier.  I also showed that, given the circuit in Figure 1, the common-mode voltage can be viewed as V2, when we consider V1-V2 as a signal that rides on top of V2.  The same goes for V1, which can be considered the common-mode voltage of the differential amplifier when -(V1-V2) is the signal that rides on top of V1.

		<description><![CDATA[In allaboutcircuits.com forum, a question was posted: How can I combine an AC source of known frequency and amplitude with a DC power supply?
I thought this is an interesting problem, so here is the solution.
