Question

Identify the logic operation carried out by the given circuit:

Options

• NOR

• OR

• NAND

• AND

Answer 1

NOR

Explanation:

From the above diagram

X = `overlineA`

Y = `overlineB`  

As the AND Gate's inputs are X and Y,

Thus, Z = `overlineA.overlineB`

According to Demorgan's theorem,

`overlineA.overlineB = overline(A + B)`

So, NOR Gate.
