Table 1 is the state table of a sequential circuit. If you are asked to design the circuit using D flip-flops, a) how many D flip-flop do you need? b) Write down the input equations for each D flip-flop. c) what are the output equations? Write them down. d) draw the circuit diagram using D flip-flop symbols.
