Construct a D flipflop that have the same charactorstics as the one shown in the figure, but instead of using NAND gates use NOR and AND gates only. (Remember that one input NOR gate is equivalent to an inverter.

A sequential circuit has three flip-flops, A, B, C; one input, x; one output, y; The state diagram is shown in the figure. The circuit is to be designed by treating the unused state as don’t care conditions. The final circuit should be analyzed to ensure that it is self-correcting. Use D flip-flop in the design. USe JK flip-flops in the design .

Design a sequential circuit with two JK flip-flops, A and B and two inputs, E and x. If E = 0 the circuit remains in the same state regardless of the value of x. When E = 1and x = 1, the circuit goes through the transactions from 00 to 01 to10 to 11 back to 00, and repeats. When E = 1 and x = 0 the circuit goes through the transactions from 00 to 11 to 10 to 01 back to 00, and repeats.

Design a sequential circuit with two D flip-flops A and B and one input, x. When x = 0 the state of the circuit remains the same. When x =1 circuit goes through the state transition from 00 to 01 to 1 to 10 back to 00 and, repeats.
