Logic Gates MCQ - Physics MCQ

The correct answer is :A = 1 , B = 1 , C = 1

An OR gate outputs a HIGH value (1) if any of its inputs is HIGH. In the case of a 3-input OR gate, there are 23=823=8 possible input combinations (since each input can be either LOW (0) or HIGH (1)).

These combinations are:

1. 000
2. 001
3. 010
4. 011
5. 100
6. 101
7. 110
8. 111

Out of these, the only combination that will result in a LOW output is the first one (000), where all inputs are LOW. In all other combinations, at least one of the inputs is HIGH, which will result in a HIGH output from the OR gate.

Therefore, out of the 8 input possibilities,7 will result in a HIGH output.

The correct answer is: Y= A + B + C + D
