Logic Gates and Programming Quiz

For which of the following combination, bulb will glow (ON):

1. A = 0, B = 1, C = 1, D = 1

2. A = 1, B = 0, C = 0, D = 0

3. A = 0, B = 0, C = 0, D = 1

4. A = 1, B = 1, C = 1, D = 0

• A = 0, B = 1, C = 1, D = 1

• A = 1, B = 0, C = 0, D = 0

• A = 0, B = 0, C = 0, D = 1

• A = 1, B = 1, C = 1, D = 0
