Truth Table Logic Expressions

The video tutorial introduces truth tables, using a two-input table with inputs A and B. It explains how inputs are represented in binary, and how to derive logic expressions from the table. The final logic expression is presented as Z = not A not B or A not B or A B.

What are the inputs labeled as in the truth table discussed?

• P and Q

• X and Y

• A and B

• 1 and 0

How do the inputs in the truth table count?

• In decimal

• In hexadecimal

• In binary

• In octal

What does a '1' in the output column of a truth table signify?

• The circuit is undefined

• The circuit is off

• The circuit is false

• The circuit is true

Which term represents the first line of the truth table?

• A B

• Not A Not B

• A Not B

• Not A B

What is the logic expression for the second line of the truth table?

• A B

• Not A Not B

• A Not B

• Not A B

What is the final logic expression for the truth table?

• Z = Not A B

• Z = A Not B

• Z = Not A Not B or A Not B or A B

• Z = A B

Which of the following is NOT a component of the final logic expression?

• Not B A

• A B

• A Not B

• Not A Not B
