Select the correct output (V₀) wave shape for a given input (V_i) in clamping network shown below—

1. (A)
2. (B)
3. (C)
4. (D)

Correct Option: D

The given circuit (i.e., fig -1)
Equivalent circuit for the first half cycle is given below (i.e., fig -2)
V₀ = 2V and V_C = 8V with mentioned polarity Now, the equivalent circuit for second half cycle is shown below (i.e., fig -3)
V₀ + 8 + 10 = 0
or V₀ = – 18V
Hence alternative (D) is the correct choice.
