4. Write down the purpose of JK flip-flops, D flip-flops, and T flip-flops Construct a sequential circuit from the given state diagram using T flip-flops. The state diagram represents a circuit that has Three Flip-Flops. The unused states should be treated as don't care conditions 146 001 1 11 000 100 1/10 1 011 / 1/1 ve / 0/1 610 0/0 1/ Fig 1: State diagram of a Sequential circuit T 0 Q 0 0 1 1 Qnext 0 1 0 1 1 1 0 Fig 2.
