-What would happen if the input signal were to go negative (below ground)?
+What would happen if the input signal were to go negative with respect to the fixed 2.5 V rail (below the common mode voltage)?
 Compare your distortion measurements for this circuit to what you measured for the previous circuit. How much have the harmonics improved?
