Boolean Logic Review

Match the following symbols with the appropriate logic gate name.

• NAND

• 
• AND

• 
• NOR

• 
• XOR

• 
• NOT

• 

Draw the logic gate symbol for an OR gate

Match the following descriptors with the appropriate gate name

• NOT

• Inverts the input signal

• AND

• Requires 2 positive inputs for a negative output

• NAND

• Requires 2 positive inputs for a positive output

• XOR

• Requires 1 or more positive inputs for a positive output

• OR

• Requires exactly 1 positive input for a positive output

Match the following truth tables with the correct logic gate

• NAND

• 
• AND

• 
• OR

• 
• NOR

• 
• XOR

• 

What would the truth table be for the following logic statement:

(A OR B) AND (NOT B)

• 
• 
• 
• 

The following NAND logic circuit is equivalent to which single gate?

• XOR

• NAND

• NOR

• AND

• OR

Consider the following logic statement:

X = 1 if ((A is 1 NAND C is 1) NOR A is NOT 1) OR (B is 1 AND C is NOT 1)

Draw a logic circuit that represents the given logic statement. Your logic gates must have a

maximum of two inputs. Do not simplify the logic statement.

Answer explanation

This would be a 6 mark question and you'd receive 1 mark for each correct logic gate with correct input(s)
