Modified Bit Parity Technique for Error Detection of 8 Bit Data

Abstract

Bit parity is often used as an error detection technique in sending digital data that has interruption during transmission. Error detection techniques allow correcting data to be error-free. Research that has been used using bit parity has been done but only detected even parity and odd parity where the process is very simple so that modifications can be made to detect other than even or odd parity. In this study a modification of the bit parity method was built in which each message received in the first 4 bits will be detected whether the bit value is a multiple of 4 and the remaining bits will be evenly detected. Error detection using the proposed parity bits results in a fairly good detection system and is more efficient if there are more bits in the message.
