[6 marks]Drawing / Sketch space
6.
Describe the function of a NOR gate in your own words.
[3 marks]7.
Identify the logic gate that outputs true only when exactly one of its inputs is true. Explain your answer.
[4 marks]8.
Draw the logic circuit diagram for a circuit that uses an AND gate and a NOT gate to produce an output that is true only when A is true and B is false.
[7 marks]Drawing / Sketch space
9.
