What is 1 XOR 1?
Short answer. 0.
What is 1 XNOR 1?
1.
XOR and XNOR
| A B | XOR | XNOR |
|---|---|---|
| 0 0 | 0 | 1 |
| 0 1 | 1 | 0 |
| 1 0 | 1 | 0 |
| 1 1 | 0 | 1 |
Remember
| XOR: 1 when inputs differ |
| XNOR: 1 when inputs match |
Which gate spots when two bits differ? Look at each row. Zero zero: same. Zero one: different. One zero: different. One one: same. XOR marks different, XNOR marks same. Two rules. XOR means different. XNOR means same.
