(A * B)(C * D) A * B + C * D A* B *(CD) (A + B)(C + D) Correct!Wrong!- Continue >> Which statement below best describes a Karnaugh map? It is simply a rearranged truth table A Karnaugh map can be used to replace Boolean rules The Karnaugh map eliminates the need for using NAND and NOR gates Variable complements can be eliminated by using Karnaugh maps Correct!Wrong!- Continue >> Which of the following statements accurately represents the two BEST methods of logic circuit simplification? Karnaugh mapping and circuit waveform analysis Boolean algebra and actual circuit trial and error evaluation Boolean algebra and Karnaugh mapping Actual circuit trial and error evaluation and waveform analysis Correct!Wrong!- Continue >> Each “1” entry in a K-map square represents: A HIGH output on the truth table for all LOW input combinations A HIGH for each input truth table condition that produces a HIGH output A LOW output for all possible HIGH input conditions A DON’T CARE condition for all possible input truth table combinations Correct!Wrong!- Continue >> Which of the following is an important feature of the sum-of-products form of expressions? All logic circuits are reduced to nothing more than simple AND and OR operations No signal must pass through more than two gates, not including inverters The maximum number of gates that any signal must pass through is reduced by a factor of two The delay times are greatly reduced over other forms Correct!Wrong!- Continue >> Which of the examples below expresses the commutative law of multiplication? A • B = B + A A • (B • C) = (A • B) • C A • B = B • A A + B = B + A Correct!Wrong!- Continue >> The Boolean expression Y = (AB)’ is logically equivalent to what single gate? NOR OR NAND AND Correct!Wrong!- Continue >> Each “0” entry in a K-map square represents: A LOW output for all possible HIGH input conditions A HIGH output on the truth table for all LOW input combinations A HIGH for each input truth table condition that produces a HIGH output A DON’T CARE condition for all possible input truth table combinations Correct!Wrong!- Continue >> The observation that a bubbled input OR gate is interchangeable with a bubbled output AND gate is referred to as: A Karnaugh map The commutative law of addition DeMorgan’s second theorem The associative law of multiplication Correct!Wrong!- Continue >> Looping on a K-map always results in the elimination of Variables within the loop that appear only in their complemented form Variables within the loop that appear in both complemented and uncomplemented form Variables that remain unchanged within the loop Variables within the loop that appear only in their uncomplemented form Correct!Wrong!- Continue >> The systematic reduction of logic circuits is accomplished by: TTL logic Using Boolean algebra Symbolic reduction Using a truth table Correct!Wrong!- Continue >> Which of the following expressions is in the product-of-sums form?
