Hi dear GATE aspirants! I am SouravMani.From today we are going to discuss Digital Electronics Questions on daily basis. hope you all co-operate and making use of it.

The logic functions implemented by the circuit below is (Ground implies a logic "0")

A) F = AND(P,Q)

B) F = OR(P,Q)

C) F = XNOR(P,Q)

D) F = XOR(P,Q)

I kindly requesting of the GATE aspirants to justify yours valuable Answers.

D is the ans

Can you please justify above..

haah... its D for sure.... good question dude... but a little bit easy right...

ya people are asking easy question also, but you dont worry we have some very tough question for you. he he

option D

hoh man... i didn't mean that...actually every one can solve easy questions right if they know the concepts perfectly... but i am telling you that whether the question is easy or tough but it should be some what tricky and thinkable dude...i am telling you that only...

hmm ok

vamshi here i left some of the part for you http://www.gate.examsavvy.com/2012/08/gate-question-of-day-general-aptitude_30.html

D

damn easy.. :)

but stil a gud one..

Dont worry dude's always begin with a easy ones from which you get confidence to go ahead!

hmm gud suggestion dude...

D is the answer

Off course many aspirants have done their suggestions/justifications well. yes guys you are obsolutely correct! The answer is option D. well done friends*

option D

I0 fed with logic 0

I1 fed with logic 1

I2 fed with logic 1

I3 fed with logic 0

Hence in order to select I1 or I2 we can have combinations either Q=0 P=1 for I1 and Q=1 P=0 for I2. So we can represent this easily by XOR between P and Q. Hence F=XOR(P,Q). :)

damn easy....:P

D is d ans.
