Question

Which one of the following is the Boolean expression for NOR gate?

Options

• Y = ${\displaystyle \overline{\text{A}+\text{B}}}$

• Y = ${\displaystyle \overline{\text{A}.\text{B}}}$

• Y = A.B

• Y = ${\displaystyle \overline{\text{A}}}$

Answer 1

Y = ${\displaystyle \overline{\text{A}+\text{B}}}$

Explanation:

Combining the NOT and OR gates results in the NOR gate. The NOR gate has the boolean expression Y = ${\displaystyle \overline{\text{A}+\text{B}}}$.
