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.
Alternate Answer
Output waveform:

57Co decays to 57Fe by $\beta^+-\text{ emission.}$- emission. The resulting 57Fe is in its excited state and comes to the ground state by emitting $\gamma-\text{rays}.$ The half-life of $\beta^+-\text{decay}$ is 270 days and that of the $\gamma-\text{emissions}$ is 10-8 s. A sample of 57Co gives 5.0 × 109 gamma rays per second. How much time will elapse before the emission rate of gamma rays drops to 2.5 × 109per second?
