EXPERIMENT 3 CLAMPING CIRCUITS EQUIPMENT REUQIRED: Diode-IN4007, capacitors, resistor,power supply,oscilloscope,function generator,multimeter,etc. • RL=100K22, C=luf EXPERIMENTAL PROCEDURE: 1. Connections are made as shown in the circuit diagram. 2. A square wave input Vi is applied. Output waveform Vo is observed on the oscilloscope. Keeping the AC/DC switch of the oscilloscope in DC Position. 3. Clamped voltage is measured and verified with the designed values. 1. Positive peak clamped at Vy level: с th lu + 수 V Vi RL IN 4007 01 100K d Vo b vr 수 주 4 V

Why are these versions of diode circuits called clamping circuits? What is the meaning of clamp? 2. What could happen if the capacity of the capacitor increased? 3. Try to explain the logic behind the result of circuits 2 and 3.
