You are required to design a 4-bit even up-counter using D flip flop by converting combinational circuit to sequential circuit. The counter will only consider even inputs and the sequence of inputs will be 0-2-4-6-8-10-0.
You are required to perform following tasks:
1. Draw the State diagram.
2. Generate State & Transition Table.
3. Generate simplified Boolean Expression.
4. Design the final Circuit diagram.
