Answer all questions in this section.
0 1 A company is designing a digital audio controller to regulate sound output in a
home theater system. The system uses three different input signals (A, B, and C)
to control the volume level via a logic circuit. The system operates using 9V logic-
compatible square waves.
0 1 . 1 Explain how the logic level applied at input B affects the output signal Q.
[2 marks]
0 1 . 2 Write the Boolean algebra expression for output Q in terms of the inputs A, B, and C.
Use only the logic operations provided in the circuit diagram. [2 marks]
