    Hello everyone, I've already known of time settings of F.F and about all circuits! .. but once I try to find the min time of any system, I just found myself stuck in, and get confused of :p ..
    I've a question that I'm struggling in it and not getting any proper result ... any help or hints please?
    the question is over this website:

    What is "Tcd"? It can't be time from clock to data, since that doesn't apply to anything other than the flip flop.

    Where is YOUR attempt to solve YOUR homework problem?

    Tcd is the lil time which remains constant as the input before the clock..

    My attempt is how to find the min T for being the system worked properly?

    T is the whole time of all times in the systems...

    So what does a "lil time which remains constant as the input before the clock" of "4" mean for a AND or an OR gate or of "1" for a NOT gate?

    Answer: Since none of these gates have a clock, it is meaningless.

    SHOW your attempt to answer the problem!

    This is YOUR homework.
