Figure 2.17. AC Voltage Measurements of the Corrected Circuit Model

Table 2.4 shows the simulated measurements of the corrected circuit and your actual measurements side by side. The

measurements are now closer to what you expected to see. If you would like to verify these results for yourself, please

use the VirtualBench Section 2_DMM and FGEN Resistor Network Corrected.ms13 file.
