15.2 Boolean Algebra and Logic Circuits Cambridge iA 9618

Which of the following is the correct truth table for an AND gate with two inputs (A and B)?

• A = 0, B = 0 → Output = 1

• A = 0, B = 1 → Output = 1

• A = 1, B = 0 → Output = 1

• A = 1, B = 1 → Output = 1

What is the output of an OR gate if both inputs are 1?

• 1

• 0

• Depends on the circuit

• Undefined

A NOT gate produces what kind of output?

• The inverse of the input

• The sum of the inputs

• The product of the inputs

• A constant 0

What is the output of an XOR gate when both inputs are the same?

• 0

• 1

• It depends on the number of inputs

• Undefined

What does a half adder circuit do?

• Adds two binary digits and produces a sum and a carry output

• Subtracts two binary numbers

• Adds multiple binary numbers at once

• Performs logical AND and OR operations

Which two logic gates are required to construct a half adder?

• XOR and AND

• OR and AND

• NOR and NAND

• XOR and NOT

Which additional gate(s) are required to build a full adder in addition to those in a half adder?

• XOR and OR

• NOR and XOR

• NAND and NOR

• NOT and AND

What is the main purpose of a flip-flop in digital circuits?

• To store a single bit of data

• To add two binary numbers

• To act as a counter

Which of the following is a type of flip-flop?

• SR flip-flop

• AND flip-flop

• XOR flip-flop

• NOR flip-flop

Which inputs does an SR flip-flop have?

• Set (S) and Reset (R)
