Question

The logic performed by the circuit shown in figure is equivalent to:

Options

• AND

• NAND

• OR

• NOR

Answer 1

AND

Explanation:

Y = `bar(bar a + bar b)`

= `bar((a * b)) a * b`

The circuit will follow the truth table:

A	B	Output
0	0	0
0	1	0
1	0	0
1	1	1

Hence, it is an AND gate.
