1. The problem statement, all variables and given/known data Draw the combinatorial circuit corresponding to the disjunctive normal form. 2. Relevant equations DNF of f(x,y,z)=xyz+Not(xy)z 3. The attempt at a solution f(x,y,z)=xyz+not(xy)z =z(xy+not(xy)) Wouldn't the xy and not xy cancel out? That's my current problem with this probelm.
