    Hi everyone,

    I was asked to determine the output Q on the timing diagram (I will assume that Q starts with 0).

    I know that the Master is active as long as the clock is high, while the Slave is on in the falling edge.

    I have drawn the output by taking the last state of J and K before the falling edge.

    I need to know whether is that right or wrong.

    hi SK,
    How does your solution compare to this state diagram for a 4027 JK Bistable

    hi,
    My posted image is the same JK layout as your two JK's in your image, so where are the differences.?:)
