The XOR gates are ideal for testing parity because even-parity words produce a _____ output and odd-parity words produce a _____ output A. low, high B. high, low C. odd, even D. even, odd E. None of the above

The correct answer is: A. low, high

An XOR gate is a logic gate that produces a high output only when its inputs are different. This makes it ideal for testing parity, which is a method of checking for errors in data. In even parity, the number of 1 bits in a word must be even. If the number of 1 bits is odd, then the parity bit is set to 1. If the number of 1 bits is even, then

To test for even parity, you can use an XOR gate to compare the word with a constant value of 1. If the output of the XOR gate is high, then the word has odd parity and an error has occurred. If the output of the XOR gate is low, then the word has even parity and no error has occurred.

Here is a table that shows the output of an XOR gate for different input combinations:

| Input A | Input B | Output |
|—|—|—|
| 0 | 0 | 0 |
| 0 | 1 | 1 |
| 1 | 0 | 1 |
| 1 | 1 | 0 |

As you can see, the output of the XOR gate is always the opposite of the inputs. This is why XOR gates are ideal for testing parity.

The other options are incorrect because they do not accurately describe the output of an XOR gate.
