A single-input logic gate that outputs output Q = 0 when input A = 0, and Q = 0 when input A = 1 is a zero-output gate. Which truth table correctly represents a standard single-input NOT gate where input A produces output Q?
- 1A = 0 → Q = 0; A = 1 → Q = 0
- 2A = 0 → Q = 1; A = 1 → Q = 1
- 3A = 0 → Q = 0; A = 1 → Q = 1
- 4A = 0 → Q = 1; A = 1 → Q = 0✓
Correct answer
A = 0 → Q = 1; A = 1 → Q = 0
