Question
Why a diode act like an open circuit? In which circumstances this occur?
CLIPPING CIRCUITS
EQUIPMENT REUQIRED:
Diode-IN4007, capacitors, resistor,power supply, oscilloscope,function generator,multimeter, etc.
Choose Rf 102, Rr-1MQ2 R=√RfRr=3.3KQ
EXPERIMENTAL PROCEDURE:
a)
Connections are made as shown in the circuit diagram.
b)
A sine wave input Vi whose amplitude is greater than the clipping level is applied.
c) Output waveform Vo is observed on the oscilloscope.
d)
Clipped voltage is measured and verified with the designed values.
