1. The problem statement, all variables and given/known data 1. Implement the following Boolean function F using no more than two NOR gates and draw the circuit.F(A,B,C,D)=∑(0,1,2,9,11)+d(8,10,14,15) 2. Implement the following Boolean function using two - level forms: NAND - AND OR - NAND and 2. Relevant equations 3. The attempt at a solution The first one is kinda easy but I didn't what's the meaning of d. The second one I'm actually Confused about the solution .First one is I draw NAND then AND is this correct.
