GATE ECE 2013 | Simple Diode and Wave Shaping Circuitsa | Analog Circuits

A voltage 1000 sin ωt Volts is applied across YZ. Assuming ideal diodes, the voltage measured across WX in Volts, is

  1. sin ωt
  2. (sin ωt + |sin ω t|)/2
  3. (sin ωt – |sin ω t|)/2
  4. 0 for all t



Answer : D
Explanation:
**The Correct Answer Among All the Options is D
Given, the input voltage


For + ve half cycle

i.e., VY is a higher voltage than VZ
So, the diode will be in cutoff region. Therefore, there will no voltage difference between X and W node.
i.e.,
Now, for –ve half cycle all the four diodes will active and so, X and W terminal is short circuited
i.e,
Hence, for all t
Hence correct option is D. Practice Topic Wise Solved ECE PSU & Gate Question for Simple Diode and Wave Shaping Circuitsa , Analog Circuits
