1 1 vote Bit stuffing is the process of inserting non information bits into data to break up bit patterns to affect the synchronous transmission of information. Flag is given as 011110 M= 1011101111011111110 Message will be transmitted as = 10111 0 0111 0 10111 0 111 0 10 Akash Mittal answered Jul 8, 2017 Akash Mittal comment Share Follow See all 12 Comments 12 12 Comments reply A_i_$_h commented Jul 9, 2017 reply Follow flag thank you :) 0 0 replyShare vamp_vaibhav commented Nov 24, 2017 reply Follow flag Still the confusion remain same should we insert after every occurrence of 0111 or 111?? 0 0 replyShare Ashwani Kumar 2 commented Nov 24, 2017 reply Follow flag See this, hope it helps 3 3 replyShare vamp_vaibhav commented Nov 24, 2017 reply Follow flag Hmmmm I agree with this way..

Check the last bits.. He has inserted 0 after 111.. Wait a minute do we have to check again after insertion that whether or not some part is matching with flag.. That's why he has inserted the last 0 0 0 replyShare Please log in or register to add a comment.
