Digital Electronics Question on Logic Gates

If ⊕ and ⊙ denote the exclusive OR and exclusive NOR operations, respectively, then which one of the following is not correct?

A

P⊕Q‾=P⊙Q\overline{P\oplus Q}=P\odot Q

B

Pˉ⊕Q=P⊙Q\bar{P}\oplus Q=P\odot Q

C

Pˉ⊕Qˉ=P\plusQ\bar{P}\oplus \bar{Q}=P\plus Q

D

(P⊕Pˉ)+Q=(P⊙Pˉ)⊙Qˉ(P\oplus \bar{P})+Q=(P\odot \bar{P})\odot \bar{Q}

Answer

(P⊕Pˉ)+Q=(P⊙Pˉ)⊙Qˉ(P\oplus \bar{P})+Q=(P\odot \bar{P})\odot \bar{Q}

Explanation

Solution

The correct answer is(D): (P⊕Pˉ)+Q=(P⊙Pˉ)⊙Qˉ(P\oplus \bar{P})+Q=(P\odot \bar{P})\odot \bar{Q}
