Question
Draw and explain the output waveform across the load resistor R, if the input waveform is as shown in the given figure.

Solution
When the input voltage is +5V, the diode gets forward biased, the output across R is +5V, as shown in figure.
Output waveform:

When the input voltage is –5V, the diode gets reverse biased. No output is obtained across R when the diode is reverse biased.
Output waveform:

When the input voltage is –5V, the diode gets reverse biased. No output is obtained across R when the diode is reverse biased.
