In this problem we are creating fixed-point 2's complement real number representations. A. Create a truth table for the expression ((a AND b) OR (C AND d) OR ( AND d)). Remember that since both AND and OR are associative, multiple ANDs or ORs at the same parenthetical depth can be evaluated in any order. (Just like when adding 2+3+4, you could start by adding 2+3 or by adding 3+4.) B. Create a truth table for the expression ((a AND (NOT b) AND (NOT c)) OR ((NOT a) AND (b OR c)))
