    This content was COPIED from BrainMass.com - View the original, and get the already-completed solution here!

    Design a synchronous counter using J-K flip-flops that will count from 0010 to 1101 repetitively.

    a) Construct the "present state - next state" truth table.
    b) Complete the required K-maps for the design.
    c) Derive the minimised Boolean expressions for the J-K inputs.
    d) Draw the logic diagram for the counter.

    Solution Preview

    a) Construct truth table increasing the binary count by 1 each time until 1101 is reached, and then revert back to 0010.

    Label the states, say DCBA for the prior state variables D, C, B and A defining this state. Label the next state with variables D+, C+, B+ and A+ so as to indicate the next count ...

    Solution Summary

    Construction of the "present state - next state" truth table is provided. The expert determines the completion of the required K-maps for the design. Derivation of the minimised Boolean expressions for the J-K inputs is determined.
