Did you ever analyses why it is happen ? then automatically you will answer to your question by yourself ! ( Hint :- Clearly observe the circuit diagram of Johnson counter diagram ) Answer to your question is :- " with out complement( i.e., keep the same value ), just perform circular right shift ! " Take care with LSB or MSB bits, according to the question you have to name it ! 1 1 replyShare amitqy commented Jan 4, 2019 reply Follow flag I never analysed it before. I just did this type of question by the long way by making tables and all. I got your point. Since in ring counter input of the first flip-flop is not complement of the output of the last flip-flop so it's just a right shift without a compliment.Thank you 0 0 replyShare Please log in or register to add a comment.
