Question

A logic gate circuit has two inputs A and B and output Y. The voltage waveforms of A, B and Y are shown below.

The logic gate circuit is ______.

Options

• AND gate

• OR gate

• NOR gate

• NAND gate

Answer 1

The logic gate circuit is AND gate.

Explanation:

When

A = 0, B = 0 ⇒ Y = 0

A = 1, B = 1 ⇒ Y = 1

A = 0, B = 1 ⇒ Y = 0

A = 1, B = 0 ⇒ Y = 0

So, this must be AND gate.
