the main advantage of half adder is that : it can not take a carry bit input from previous stage select one: O True di False An essential prime implicant is a product term obtained by combining the maximum possible number of adjacent squares in the map. Select one: O True O False Refer to figure 2, carefully, analyze the sequential circuit which contains 2X4 active low decoder decoder, two 2X1 Mux, and UK flip-flop then answer the following questions: what is the Boolean state equation for Q(t.1). "note A: is the most significant bit. C: least significant bit in the state table. ** its best for you to draw the state table. 2x FI 2 . DR EU A de cada O a. Q(t+1)=F2 XOR Q' O b. Q(t+1)=Q'F1+QF2 O c. Q(t+1)=F1 XOR Q O d. Q(t+1)=F1 XOR F2
