ok, so im studying for a test and i just cant seem to figure out how to solve this problem, help if u can...

a.) Find a minimum two-level NOR gate circuit to realize F1 and F2. Use as many common gates as possible.

F1 (a,b,c,d) = Σm (1,2,4,5,6,8,10,12,14)

F2 (a,b,c,d) = Σm (2,4,6,8,10,11,12,14,15)

b.) Realize F1 and F2 using a PLA. Give the PLA table and internal connection diagram for PLA.
