Question
Draw and explain the output waveform across the load resistor R, if the input waveform is as shown in the given figure.
✓
Answer
If the candidate considers it as a circuit containing diode.Wave form:
Explanation:
When the input voltage is +5v, the diode, being forward biased, conducts and output is obtained across R. When the input is –5v, the diode being reverse biased does not conduct and hence there is no output.
Alternate Answer
If the candidate considers it as a circuit with NOT gate.
Wave form:
Explanation:
When the input is zero, NOT gate conducts and output is obtained across R.
When the input is 5V there will be no output.
