Homework Help: Primitive Flow table

  1. Apr 19, 2015 #1
    1. The problem statement, all variables and given/known data
    Following the amount of C1 front, the output Z be 1 .
    Following an amount of C2 front, the output Z must be 0 .
    Otherwise, the output remains unchanged.

    2. Relevant equations

    3. The attempt at a solution
    in Attached file.

    This is the answer but I really do not understand the concept of how it works and how I actually have to look at it.

    For example on the row S2: S2 is the stable state(10), it can reach S4(11) and S5(00)
    I dont understand why the output is 1 because my stable state C1 is 1 which make it impossible for a amount of C1 front, it would of require it to be 0 then change to 1 on either S4 or S5 which is not the case.

    Do I have to read it the other way around? my transition to my stable state? in that case S5 (C1=0) so there would be a amount of C1 front to the stable state.

    Also I dont understand why the row S3 and S4 is not the same output since the stable state is in the same location on both row so C1 and C2 logic condition must be the same on each row?

    thanks for helping me this is all extremely confusing me and I tried really hard in 3 days to understand it :/

    I don't understand those statements. What does "the amount of C1 front" mean?
