Please solve Question 3
Question 3 (5 points) Consider the logic circuit given below: 1- Make the truth table of the inputs A, B, C and D,and output S. 2. Deduce thesimplified Boolean expression of S using K-map. 3- Find the expression of Susing Boolean algebra. AB (6)(bec S Boc (A1B) (BOC) -7 CD D (7 points) Question 4 We want to design a synchronous counter with incomplete cycle. For this, we propose a modulo-9 counter using JK flip-flops. M 1- How many flip-flops are required to make this counter? I N=4 2- Give the excitation table showing the present states, the next states, and the JK flip-flop inputs, 3- From this table, determine the simplified logic expressions of the inputs Ji and Ki as a functionof Oi. 4- Construct the logic diagram of this counter Good Luck
