An error-correction scheme appends a parity bit to each data byte to form code word and the sequence of 15 code words is followed by a longitudinal redundancy check (LRC) code word to orm a data packet.The resulting DIF = ____ .

Question

Quizplus · Accepted Answer

The Answer is 1.2.Each code word contains 9 bits of which 8 bits are data.Each data packet contains 16 code words of which 15 contain data.

ext { DIF } = ( 9 imes 16 ) / ( 8 imes 15 ) = 1.2
