Exam-style question
Try this first
Inverting amplifier ? choose the statement about signal polarity. Use this to support: Explain why synchronisation is needed.
- A.inverting amplifier: the output is inverted because negative feedback is applied to the inverting input for Time-division multiplexing.
- B.inverting amplifier: says the output has the same phase.
- C.inverting amplifier: uses a diode explanation.
- D.inverting amplifier: ignores feedback entirely.
Model answer
What a good answer should say
- The correct option is inverting amplifier: the output is inverted because negative feedback is applied to the inverting input for Time-division multiplexing.
Explanation
Why this works
This is the best answer because the inverting amplifier context requires that exact electronics relationship. The other options are incorrect because they use a different component, reverse the circuit behaviour, or omit the output interpretation required for Time-division multiplexing.
