Write down the Boolean expression for the following logic circuit

• 𝑄 = (𝐴 * 𝐵) . 𝐵

• 𝑄 = (𝐴 + 𝐵) . 𝐵

• 𝑄 = (𝐴 * 𝐵) . 𝐵'

• 𝑄 = (𝐴 + 𝐵) . 𝐵'

Write down the Boolean expression for the following logic circuit: A AND (B OR C)

• 𝑄 = (𝐴 + 𝐵) * 𝐶

• 𝑄 = 𝐴 + (𝐵 * 𝐶)

• 𝑄 = (𝐴 * 𝐵) + 𝐶

• 𝑄 = 𝐴 * (𝐵 + 𝐶)

Write down the Boolean expressions for NOT gate

• X=A'

• X=A+B'

• X=AB'

• X=AB
