Logic Gates

What is the truth table for an AND gate?

• Inputs: 0,0 -> Output: 0; Inputs: 0,1 -> Output: 0; Inputs: 1,0 -> Output: 0; Inputs: 1,1 -> Output: 1.

• Inputs: 0,0 -> Output: 1; Inputs: 0,1 -> Output: 0; Inputs: 1,0 -> Output: 0; Inputs: 1,1 -> Output: 0.

• Inputs: 0,0 -> Output: 0; Inputs: 0,1 -> Output: 1; Inputs: 1,0 -> Output: 0; Inputs: 1,1 -> Output: 0.

• Inputs: 0,0 -> Output: 1; Inputs: 0,1 -> Output: 1; Inputs: 1,0 -> Output: 1; Inputs: 1,1 -> Output: 1.

What is the truth table for a NOT gate?

• Input: 0 -> Output: 1; Input: 1 -> Output: 0.

• Input: 0 -> Output: 0; Input: 1 -> Output: 1.

• Input: 0 -> Output: 1; Input: 1 -> Output: 1.

• Input: 0 -> Output: 0; Input: 1 -> Output: 0.

What is the output of a NAND gate with inputs 1 and 1?

• 0

• 1

• undefined

• error

What does an OR gate do?

• Outputs a 1 if at least one of its inputs is a 1.

• Outputs a 1 only if all its inputs are 1.

• Outputs a 0 if at least one of its inputs is 0.

• Outputs a 1 if none of its inputs are 1.

What is the output of an AND gate with inputs 1 and 0?

• 0

• 1

• 1.5

• -1

How do OR and XOR gates differ?

• An OR gate outputs a 1 if one or more inputs are 1, while an XOR gate outputs a 1 if only one (not both) of the inputs is 1.

• An OR gate outputs a 1 only if both inputs are 1, while an XOR gate outputs a 1 if at least one input is 1.

• An OR gate outputs a 0 if any input is 1, while an XOR gate outputs a 1 if both inputs are 0.

• An OR gate and an XOR gate function identically in all cases.

What is the output of a NOT gate with input 0?

• The output is 0.

• The output is 1.

• The output is undefined.

• The output is 2.

What is the output of a NOR gate with inputs 0 and 0?

• 0

• 1

• undefined

• error

What is a NAND gate?

• A gate that outputs 1 only if all inputs are 0.

• A gate that outputs 0 only if all inputs are 1; otherwise, it outputs 1.

• A gate that outputs 1 if at least one input is 1.

• A gate that outputs 0 if at least one input is 0.

What does a NOT gate do?

• A NOT gate outputs the same value as its input.

• A NOT gate outputs the opposite value of its input; if the input is 1, the output is 0, and vice versa.

• A NOT gate outputs a constant value regardless of its input.

• A NOT gate doubles the input value.
