Now, we are going to create what’s called an XOR gate, an exclusive or gate. This gate receives two inputs, a and b, and only returns a 1 if one of the inputs is 1, but not if both of the inputs are 1.
To build your XOR_gate(), you should use any combination of the gates you’ve already made: NAND_gate(), NOT_gate(), AND_gate(), and OR_gate().
Here’s the truth table:
| a | b | output |
|---|---|---|
| 0 | 0 | 0 |
| 0 | 1 | 1 |
| 1 | 0 | 1 |
| 1 | 1 | 0 |
Instructions
1.
Define XOR_gate() which takes two inputs, a and b, and returns the outputs specified in the truth table.
