![3. With the oscilloscope, measure the peak output voltage V,(rect) and the ?
peak-to-peak ripple voltage across the 1-k resistor and the 100-µF capac-
itor. With your multimeter, measure the de voltage (VDc) and compute the
expected de voltage, peak-peak ripple, and percentage ripple using Equa-
tions 1, 2. and 3. Record all results in Table 3-1.
