If 3 flip flop how to plot state diagram ,transition table ?

[@harshabk3863]

Kiran you can find one such example numerical in this link sites.google.com/a/cmrit.ac.in/harsha_bk/information-theory-coding/notes/module-wise-class-notes

[@Eng_Subjects_Matad]

sir it is better to consider 00-S0 , 01-S1, 10-S2 , 11-S3 i think...

[@harshabk3863]

No, dear. Ideally, 01 can never come before 10 in real-time applications. Kindly watch the complete video. I hope things will be clear.

[@harshabk3863]

Kindly watch the video at 5:00 to get a better idea of it.

[@Eng_Subjects_Matad]

Sir ... I think it does not matter a lot... Because we are assuming input 0 or 1 ... If assume begining input is 1 we will get different state... Usually while writing state table .. What i observed in all videos / what i heard from my lecture is they consider 00-S0, 01-S1, 10-S2 and 11-S3 or 00-a, 01-b, 10-C and 11-d.

[@harshabk3863]

This is not about the four combinations as the weighted code as
2^1 2^0
0 0
0 1
1 0
1 1
Here the discussion is about the shift registers. FF1 is the 1st flipflop and it feeds the 2nd flipflop designated as FF2. ∴ the sequences have to be proper. Though you can name the way as per wish.
in FF1 FF2 State Comments
0 0 s0 Power on reset
0 0 0 s0 Already designated, hence no need to write the same again.
1 1 0 s1 First new state possible
1 0 s1 Inputs can be either 0 or 1.
0 0 1 s2 second new state possible.
1 1 1 s3 third new state possible.
Only thing is s2 and s3 can be interchangeable as
1 0 s1 Inputs can be either 0 or 1.
1 1 1 s2 second new state possible.
0 0 1 s3 third new state possible.
Beyond this all the states will among the above four states.
Also 01 can never appear before 10, as these are shift register contents. But designating it as s1/s2 or b/c is immaterial.
Hope this clears the confusion.
