Card 1
Question: What are digital systems like calculators and computers built upon?
Answer: Fundamental components called logic circuits.
Card 2
Question: What kind of information do logic circuits process?
Answer: Binary information, consisting of two states: 0 (false, low voltage) and 1 (true, high voltage).
Card 3
Question: What is a combinational logic circuit?
Answer: A type of digital circuit where the output at any given time depends solely on the current input values, with no memory of past inputs.
Card 4
Question: What is often the first step in designing a combinational logic circuit?
Answer: To define its behavior using a truth table.
Card 5
Question: What is a truth table used for in logic?
Answer: To compute the functional values of logical expressions on all their possible input values by systematically listing all possible combinations of inpu
Card 6
Question: What is the mathematical foundation for digital logic?
Answer: Boolean algebra.
Card 7
Question: What are the two standard forms typically used to derive a Boolean expression from a truth table?
Answer: Sum of Products (SOP) or Product of Sums (POS).
Card 8
Question: When creating a Sum of Products (SOP) expression, which rows in the truth table are considered?
Answer: Rows where the output is 1.
Card 9
Question: In SOP form, what is a 'minterm'?
Answer: An AND term where each input variable appears once, either in its true form (if the input is 1) or its complemented form (if the input is 0).
Card 10
Question: How are minterms combined to form the final Boolean expression in SOP form?
Answer: They are ORed together.
