For the given circuit (shown in part (A)), the time dependent input voltage and corresponding output are shown in part (B) and part (C), respectively. Identify the components that are used in the circuit between points X and Y. [2026]

For the +ve half cycle of input: Middle branch has ideal diode in forward bias and Zener diode in reverse bias. Thus, we get constant 5 V output due to Zener breakdown. For this situation component between X and Y should act as open circuit.
For −ve half cycle of input: Middle branch has ideal diode in reverse bias, which makes it open branch without any current. For this situation component between X and Y should give a constant −5 V output due to Zener breakdown.
(Note: The input side must contain some resistance else is equal to for every cases)
