1. Set up the circuit as shown in Fig. 7.5, using the 5.1kΩ resistor and the silicon diode. Connect the unmarked anode of the diode to the positive terminal of the signal generator. Choose the sine wave on the function generator and set the frequency to 100 Hz. Connect the oscilloscope probe across the resistor and press the AutoRange button to observe the waveform on the screen. Draw the waveform below for reference for your lab report. Explain why the signal measured across the 5.1kΩ resistor looks as it does. 2. Use the oscilloscope to measure the peak-to-peak voltage of this half-wave rectified sine wave. 3. The average value of a half-wave rectified sine wave is given by Eq. 7.7. Take the peak-to-peak voltage from the oscilloscope and calculate the average voltage using Eq. 7.7. Vavg ​=π1​Vo​ 4. Use a DC voltmeter to measure the voltage of the half-wave rectified sine wave. How does the voltmeter result compare to the calculation done in the previous step? 5. Note that the half-wave rectified sine wave is a DC signal. It is not a smooth signal with a constant de value, but its voltage does not alternate from positive to negative as the original sine wave did. By using a second diode, a full-wave rectified signal can be obtained, and by using four diodes in a bridge configuration, a smoother, more constant valued signal can be obtained.
