Announcement :
1. Clamper handout contains 4 clamper circuit analysis/design, please complete the remaining 2 Clamper circuits with constant voltage model on your own following on similar lines as given in clamper handout.
2. Without resistor present in a clamper circuit is called an Ideal Clamper.
3. Practical clamper circuits have resistors connected as shown in image above With One Condition
(Condition: RC time constant should be large enough to ensure that voltage across capacitor does not discharge significantly during the period the diode if OFF. )
4. Add this condition as assumption in your clamper answers when asked in exam.
