An OR gate has 6 inputs. The number of input words in its truth table are________________?
Correct answer: C. 64
- A. 6
- B. 32
- C. 64
- D. 128
Explanation
A truth table for n inputs has 2^n possible input combinations, since each input can independently be 0 or 1. For six inputs, this gives 2^6 = 64 words.
