Lecture 3: Error Detection Code (Parity Generator & Checker)
Показать описание
#ErrorDetectionCode, #ParityGenerator, #ParityChecker
An error detection code is a binary code that detects digital errors during transmission. The detected errors can not be corrected but their presence is indicated. The most common error detection code used is the parity bit.
A parity bit(s) is an extra bit that is added with original message to detect error in the message during data transmission.
Even Parity: One bit is attached to the information so that the total number of 1 bits is an even number.
Odd Parity: One bit is attached to the information so that the total number of 1 bits is an odd number
Parity Generator:A parity generator is a combinational logic circuit that generates the parity bit in the transmitter.
Parity Checker: A circuit that checks the parity in the receiver is called parity checker.
A combined circuit or devices of parity generators and parity checkers are commonly used in digital systems to detect the single bit errors in the transmitted information
