Design Mod-3 synchronous counter. [5]
A Mod-3 counter counts in the sequence: 0 → 1 → 2 → 0 → 1 → 2 → ... It requires 2 flip-flops (since 2^2 = 4 ≥ 3) and uses JK flip-flops (standard design approach). --- Present State Next State :---::---: Q1 Q0 Q1+ Q0+ 0 0 0 1 0 1 1 0 1 0 0 0 1 1 X X (invalid/unused) --- Recall the JK excitation t...
