Expert Solution & Answer
Chapter 3, Problem 15RQ
Explanation of Solution
Usage of parity bits:
- • In PLC, the accuracy of transmission of data has to be checked to verify whether it is corrupted or not during transmission.
- • For this purpose, a parity bit is used.
- • Parity bit is used to detect errors which occur while a word is being moved.
- • In this technique, an additional bit of either “0” or “1” known as the parity bit is added based on the number of characters of the data...
