A synchronous counter using two J – K flip flops that goes through the sequence of states: Q1 Q2 = 00 → 10 → 01 → 11 → 00 …. is required. To achieve this, the inputs to the flip flops are

J1 = Q2, K1 = Q2’; J2 = 1, K2 = 1

J1 = Q2, K1 = 0; J2 = Q1’, K2 = Q1

J1 = 1, K1 = 1; J2 = Q1, K2 = Q1

J1 = Q2’, K1 = Q2; J2 = Q1, K2 = Q1’
