Design a circuit using D flip-flops that will generate the sequence 0, 0, 1, 0, 1, 1 and repeat. Do this by designing a counter for any sequence of states such that the first flip-flop takes on this sequence. There are many correct answers, but do not duplicate states, because each state can have only one next state. Discuss your design process with other students and comment on other students' designs.

The steps are outlined below:

Explanation:

Let the circuit be a 3-bit counter, the number of flip flops being required = 3

Then, the next stage is to let the type of flip-flops be the RS flip-flops.

Afterwards, let the three flip flops be A, B, C.

Then, state the table for the circuit excitement.

After the excitement table, transfer the RS flip flops from the excitation table to the Karnaugh maps.

The final step is to implement the combination logic from the equations and connect the flip flops to form a sequential circuit. Then you will have a complete binary counter.
