If the peak-to-peak voltage of a sinusoidal waveform extends vertically 6.4 divisions and the oscilloscope vertical sensitivity was set to 0.5 volts/division, what would be the reading of a multimeter using both the AC and DC scales? Assume the there is no DC offset on the sinusoidal waveform. The multimeter AC voltage measurement is displayed in RMS. (Note: Review Section 11.4 in Alexander and Sadiku).
