Additional Error Reduction by Connecting a Series Resistor

The additional error due to the DC voltage source noise can be reduced by connecting a series
resistor. Figure 8-6 to Figure 8-9 show esminations of 10% additional error when the 0 (no
series resistor), 5 k , 10 k , 50 k ,
and 100 k series resistor is connected.
