A sequential circuit has three flip-flops, A, B and C; one input x and
one output z.
The state diagram is shown in figure below. First, minimize (if possible) the state
diagram shown in figure below. The circuit is to be designed by treating the
unused states as don?t care conditions. The final circuit is to be
analyzed to ensure
that it is self correcting. Use JK FF for the design.
