Questions
Answer the following questions on the worksheet.
1. What would be different about the signal waveforms if the diode D1 is reversed?
2. Why would an individual desire to use a capacitor after the diode rectifier? What impact does the value of the capacitor have on the filter rectified circuit?
3. For negative voltages, what voltage regulator(s) would you suggest to use?
4. If an individual needs a positive voltage other than 5 V, what voltage regulator would you recommend? What must be the regulator input voltage for this voltage regulator to operate properly?
