3. (6 points) Consider the circuit below BI A) Derive the equation F for the circuit above. List all the input pairs of ABCD, where a transition between the two can cause a static-1 hazard Design a hazard-free circuit that generates the same steady value as F Show that the optimal product of sums implementation of F does not experience any static- 0 hazards B) C) 4. (7 points) The following logic function is given as a sum of minterms F(A,B,C,D) 2 A,B,C,D(0,1,4,5,9,11,13,15) A) Find out SOP for the function B) List all the input pair(s) where we can observe a timing hazard from the K-map. C) Draw the timing hazard diagram for one of the input pair. Assume ALL gate delays are equal ldentify the timing hazard from the diagram. Write the expression of an equivalent logic function in which the timing hazard(s) is/are eliminated. D)
