Add one more J-K flip-flop to convert the MOD-5 ring counter in Problem 7-73 into a MOD-10 counter. Determine the sequence of states for this counter. This is an example of a decade counter that is not a BCD counter. Draw the decoding circuit for this counter.

Data from Problem 7-73

Draw the diagram for a MOD-5 ring counter using J-K flip-flops. Make sure that the counter will start the proper count sequence when it is turned on.
