    Hello,
    It was a question in exam. Design T flip-flip from S-R flip-flop and state the modification that should be applied on the pulse going to the T input.

    any ideas?

    thanks.

    T flip flop = toggle the output (on each clock edge when T is high). Take a look at the SR truth table and see what input is required. Is that input similar to one of the outputs (Q or Qbar)?

    Since an SR is not clocked and a T is clocked I'm going to be interested in how this might be done. Without thinking about it too hard, I'm going to say I don't think it is reasonable to even pose the problem.
