Half-Wave Rectifier Circuit 1. Build the half-wave rectifier circuit of figure 9, using the bench function generator to provide Vi. Make sure the scope is dc coupled so that you can see both the ac and dc components of the signal. Adjust the dc offset of the function generator until the dc component of Vi is zero. 2. Connect the scope to both the input and output to see the effect the circuit has on Vi. Sketch the waveforms of Vi and Vo below. Recall that a dc voltage is simply the average value of the voltage. In part 1, you adjusted the dc voltage, or average value, of Vi to zero. The resulting signal is symmetrical about the zero baseline. Look at the scope display of Vo. Does it have a zero dc voltage? Use the multimeter to measure the dc voltage of Vo (across the 2.2 KΩ resistor). Vo dc = 2.84V Clipping Circuit 1. Build the clipping circuit on the designer board, using the bench function generator to provide Vi, and the designer board’s adjustable dc power supply to provide Vref. Before
