3. You are given the following state table. Input A 0 0 Present State Output B(t) C(t) X Y 0 0 1 0 0 1 0 0 Next State B(t+1) C(t+1) 1 1 1 1 1 0 1 1 1 1 0 0 1 1 1 0 0 1 0 1 0 0 0 1 0 0 0 0 1 0 1 1 1 1 0 1 1 1 1 1 (i) (5] Draw the state diagram. 0 0 0 1 1 (ii) [8] By using K-maps, find the functions for X, Y, B(t+1) and C(t+1). (iii) (7] Draw the sequential circuit (You need to consider D flip-flops as memory unit)
