JEE Main 2021 · 31 August · Evening Shift · Physics · Semiconductors
If V _ A and V _ B are the input voltages (either 5V or 0V ) and V...
If are the input voltages (either )
Options
- AOR and NOT Gate
- BAND and NOT Gate
- CAND and OR Gate
- DNAND and NOR Gate
Correct answer
A. OR and NOT Gate
Step-by-step solution
In the above circuit is we are applying high voltage in any one of the diodes or in both diodes simultaneously then we get a high out due to forward biasing of diode while we are applied low voltage in both the diode then we get low voltage so this is like OR gate.
In the above circuit which is an NPN transistor in a common emitter configuration having a phase difference of between input voltage and output voltage, when we are applied high voltage then we get low voltage vice-versa so, the circuit is the same as NOT gate.
