3. The following logic function is given as a sum of minterms F(W,X,y,z) - w.x,yz(1, 3, 5,6,7,14) a) What is the minimal sum-of-products expression of this function? b) Draw the circuit implementing this expression c) Give all input pair(s) where a transition between them would create a timing hazard d) Draw the timing diagram showing the hazard for one of the cases. Assume ALL gate delays are equal. e) Provide the expression of an equivalent logic function in which the timing hazard(s) is/are eliminated 4. For the logic expression F = wNZ + Y,Z' + XY (NOTE: this is not necessarily an optimized function) a) List all the input pairs of WXYZ, where a transition between the two can cause a static-1 hazard b) Design a hazard-free circuit that also produces the same steady-state value as F c) Show that the optimal product of sums implementation of F does not experience any static-0 hazards
