If a 3-input OR gate has eight input possibilities, how many of those possibilities will result in a HIGH output?

Detailed Solution for Logic Gates MCQ - Question 2

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.
