Test: K-Map Simplification - Question 1

Which statement below best describes a Karnaugh map?

Detailed Solution for Test: K-Map Simplification - Question 1

K-map is simply a rearranged truth table. It is a pictorial representation of truth table having a specific number of cells or squares, where each cell represents a Maxterm or a Minterm.

Test: K-Map Simplification - Question 2

The Boolean expression Y = (AB)’ is logically equivalent to what single gate?

Detailed Solution for Test: K-Map Simplification - Question 2

If A and B are the input for AND gate the output is obtained as AB and after inversion we get (AB)’, which is the expression of NAND gate. NAND gate produces high output when any of the input is 0 and produces low output when all inputs are 1.

Test: K-Map Simplification - Question 3

The systematic reduction of logic circuits is accomplished by _______________

Detailed Solution for Test: K-Map Simplification - Question 3

The systematic reduction of logic circuits is accomplished by using boolean algebra.

Test: K-Map Simplification - Question 4

Each “0” entry in a K-map square represents _______________

Detailed Solution for Test: K-Map Simplification - Question 4

Each “0” entry in a K-map square represents a LOW output for all possible HIGH input conditions. Thus, it represents Maxterm.

Test: K-Map Simplification - Question 5

Looping on a K-map always results in the elimination of __________

Detailed Solution for Test: K-Map Simplification - Question 5

Looping on a K-map always results in the elimination of variables within the loop that appear in both complemented and uncomplemented form.

Test: K-Map Simplification - Question 6

Which of the examples below expresses the commutative law of multiplication?

Detailed Solution for Test: K-Map Simplification - Question 6

The commutative law of multiplication is (A * B) = (B * A).
The commutative law of addition is (A + B) = (B + A).

Test: K-Map Simplification - Question 7

The observation that a bubbled input OR gate is interchangeable with a bubbled output AND gate is referred to as _________

Detailed Solution for Test: K-Map Simplification - Question 7

DeMorgan’s Law: ~(P+Q) <=> (~P).(~Q) Also,
~(P.Q) <=> (~P)+(~Q).

Test: K-Map Simplification - Question 8

Each “1” entry in a K-map square represents ________

Detailed Solution for Test: K-Map Simplification - Question 8

Each “1” entry in a K-map square represents a HIGH for each input truth table condition that produces a HIGH output. Thus, it represents a minterm.

Test: K-Map Simplification - Question 9

Which of the following statements accurately represents the two BEST methods of logic circuit simplification?

Detailed Solution for Test: K-Map Simplification - Question 9

The two BEST methods of logic circuit simplification are Boolean algebra and Karnaugh mapping. Boolean Algebra uses the Laws of Boolean Algebra for minimization of Boolean expressions while Karnaugh Map is a pictorial representation and reduction of the Boolean expression.

Test: K-Map Simplification - Question 10

Which of the following expressions is in the sum-of-products form?

Detailed Solution for Test: K-Map Simplification - Question 10

Sum of product means that it is the sum of all product terms. Thus, the number is multiplied first and then it is added: A * B + C * D.
