Design clocked sequential circuit of the following state diagram by using JK flip-flop

Question

Suresh Chand · Accepted Answer

From the state diagram two flip-flips are needed to represent the four states and are designated QoQ1. The input variable is labelled x State Table: Present State Next State Q0 Q1 X = 0 X = 1 Q0 Q1 Q0 Q1 0 0 0 1 0 0 0 1 0 1 1 0 1 0 1 1 1 0 1 1 1 1 0 0 Excitation Table using j-k Flip-Flops Present State Input Next State Flip-flop inputs Q0 Q1 x Q0 Q1 J0 K0 J1 K1 0 0 0 0 1 0 x 0 x 0 0 1 0 0 0 x 0 x 0 1 0 0 1 0 x x 0 0 1 1 1 0 1 x x 1 1 0 0 1 1 x 0 1 x 1 1 0 1 1 x 0 x 0 1 1 1 0 0 x 1 x 1 K-map simplification For J0: For K0: For J1: For K1: The logic diagram of the sequential circuit is
