4(Timing Hazards).Using K-map, find all of the static hazards in the following circuits.For each ofFandFi) draw the K-map, ii) find the hazards (i.e.,static-1 hazardorstatic-0 hazard)12and its type, iii) derive the new hazard-freeFnewandFnew, and iv) draw the circuit diagram for12newnewFandF. Assume that onlyw,x,y, andzare available and their complements areNOT12available.1.F(w, x, y, z) =wx+wy.[Points:10]12.F(w, x, y, z) = (w+x)(y+z)(w+x+y+z)(w+x+y+z).[Points:10]
