Why do logic designers prefer NAND and NOR gates to AND and OR gates? 7.  What is the difference between positive and negative logic? 8.  Use axioms and theorems of switching logic to prove X + X' · Y + X' · Y · Z = X + Y. 9.  Now, use a truth table to verify the previous equation. 10.  Use deMorgan's theorem again and again on this expression, until every negation is over only one term. ((A · H + B') · F' · (C' · D' + E)' · G')' 11.  Rewrite the following as the algebraic sum of minterms, and then again as the algebraic product of maxterms. A · B + A · C + B · C +CD...
