The logic circuit shown below has the input waveforms 'A' and 'B' as shown. Pick out the correct output waveform
.

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
A

The output of the circuit is
`Y=bar(bar(A)+bar(B))=bar(bar(A)).bar(bar(B))=A.B" (By de Morgan.s theorem)"`
It is the Boolean expression of AND gate.
The output waveform corresponding to given input waveforms A and B is as shown below.
