Sir if constraint length changes will current state changes to s3 s2 s1 ah sir???

[@PASSIONATEPROFESSOR]

Constraint Length is just the number of shifts. It is not related to current state changes

[@silambamjayasri]

@@PASSIONATEPROFESSOR means we have to consider s2 s1 in current state for all the problems ah sir ? No matter how many shifts are given we have to consider only two states in current state right??

[@PASSIONATEPROFESSOR]

@@silambamjayasri Yes. Most probably they will give only constraint length 3. You consider s2 and S1 as current state so that you don't get confused but the real operation is different if you go through thaat you will get confused. Remember for all the problems the next date will repeat a, b, c, d only the output will vary so if the output is correct problem will be correct.

Thank you sir
Clear explanation 🤩

Sir should we put. Code tree and code trellis using the OUTPUT SEQUENCE ???

[@PASSIONATEPROFESSOR]

No ma. Ouput sequence is different. You should draw code tree and code trellis from the given diagram or equations give in the question. Go through the middle part of the video where o have explained a complete problem
